9747d87ff6 [frontend] Added a handful of options to force the frontend to assert or crash.
Added -debug-assert-immediately and -debug-crash-immediately, which cause an
llvm_unreachable or LLVM_BUILTIN_TRAP to execute during argument parsing.

Added -debug-assert-after-parse and -debug-crash-after-parse, which cause an
llvm_unreachable or LLVM_BUILTIN_TRAP to execute after calling
CompilerInstance::performParse().

This fixes <rdar://problem/16013025>.

5c696fda8b Make IR generation take an explicit LLVMContext.
Prior to r13134, the modules being constructed for IRGen always used the
LLVM global context due to <rdar://problem/15283227>, but the interface
should really take this as a parameter rather than baking the behavior
into IRGen.

10efd0b073 Add SILOptions as an argument to runSILDiagnosticPasses.
I am going to use this in a forthcoming patch which creates a special mode
called "ParanoidVerification" which runs the verifier after all passes.
"ParanoidVerification" will be by default off and will be used on the swift-fast
buildbot to help catch bugs which might be hidden by optimizations being run.

6af4dbf0e9 Move SILLinkMode to SILOptions.
SILSerializeAll and EmitVerboseSIL are /not/ being moved because they are
options controlling the output, not about SILGen and SIL passes.

No functionality change.

c7f1064527 Extract '-sil-inline-threshold' from the performance inliner.
Plumbing this through to the inliner necessitated the creation of a
SILOptions class (like FrontendOptions and IRGenOptions). I'll move
more things into this soon.

One change: for compatibility with the new driver, the option must be
specified as "-sil-inline-threshold 50" instead of "-sil-inline-threshold=50".
(We're really trying to be consistent about joined-equals vs. separate
in the new frontend.)

e37d2393d1 Modules containing SIL may not be emitted before SIL diagnostics.
...and probably should not be emitted before optimization passes.
The new frontend got this wrong, and the old one pretended to allow it but
then silently didn't write a module at all.

f165afe1aa Replace "-enable-sil-linking=false" with "-disable-sil-linking".
Also, restructure so that the option isn't declared in a random library file.
(And do the same with "-sil-link-all".)

Part of the migration to the new driver.

d69b305200 Generate IR for inline functions from Clang modules.
Currently only inline functions referenced from Swift source files, or
from the REPL, will get IR generated for them. Inline functions
referenced by other inline functions will require additional effort to
generate properly.

With this change we use the clang::CodeGenerator-created llvm::Module
for all IR generation in Swift. This is perhaps undesirable, but
unavoidable given the interface the public Clang APIs expose, which do
not allow for building a ModuleBuilder that borrows an existing
llvm::Module.

Also unfortunate is the hack to generate a UsedAttr for each imported
inline function, but the public Clang APIs do not provide a way to only
emit deferred decls without emitting other things (e.g. module flags
that conflict with what the Swift IRGen emits). Note that we do not do
IRGen for every inline function in the module - only the ones that the
importer pulls in, which appears to be only those transitively
referenced from Swift code.

5e40837b62 Always pass an llvm::Module* to performIRGeneration().
Previously it would create a new module if one was not passed in. There
are no uses where we do not or cannot provide a module, so it seems
reasonable to make the interface consistently require a module.

c312e51962 Add the ability to serialize modules with LLDB's wrapper info around them.
Currently when compiling with debug info, the AST gets serialized into the
.o file for use by the debugger. However, when we switch to one .o file
per .swift file, this won't really make sense any more. Instead, we should
collect all the ASTs at the end of the build and merge them together, then
write /that/ into the final binary.

This commit handles writing a serialized AST with an LLDB wrapper around it,
so that we can take a merged AST, write it out in the wrapper, and splice it
into the final binary using ld's -sectcreate option.

In the long run, we probably won't need the LLDB wrapper, but for now I'm
trying to disturb as little as possible. (It looks like the layout is
broken on 32-bit platforms, though...there was a problem with 64-bit
relocations in the existing SwiftASTStreamerPass, but nothing ever tried to
/read/ the new layout in 32 bits. I'm holding off on dealing with this
right now.)

11008f0ed1 Split diagnostics out into separate files.
Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.

No functionality change, but should speed up compile times!

3a1810336e [frontend] Implement support for emitting modules with the integrated frontend.
Added support for the -emit-module and -module-output-path options. -emit-module
and -module-output-path function similarly to -serialize-diagnostics and
-serialized-diagnostics-path: notably, -module-output-path implies -emit-module,
but -emit-module can be passed without -module-output-path and a default path
will be determined based on other inputs.

Added support for the -module-link-name option, which specifies the name of the
library to link against when importing the generated module.

Note that support for these options is only implemented in the integrated
frontend; driver-level support for these options is forthcoming.

00f076daa5 [frontend] Implemented support for emitting serialized diagnostics.
Reworked the -serialize-diagnostics option, so that it is now just a flag
indicating that the frontend should generate serialized diagnostics. The path at
which the diagnostics will be serialized is now specified by the
-serialized-diagnostics-path option, which is a frontend-only option. (The
frontend treats -serialized-diagnostics-path as implying -serialize-diagnostics.)

If -serialize-diagnostics is passed but -serialized-diagnostics-path is not
passed, the frontend will choose an output path from a few default values:

- If the frontend has a non-stdout output path, replace that path's extension
  with .dia.
- If there is a primary input filename, use that input's base name as the base
  name for the serialized diagnostics file.
- Otherwise, use the module name as the base name for the serialized diagnostics
  file.

Added support for setting up a serialized diagnostics DiagnosticConsumer in
frontend_main() if FrontendOptions::SerializedDiagnosticsPath is non-empty.

53a0acad66 [frontend] Added temporary support for setting MainInputFilename, Triple, and OutputFilename in IRGenOptions.
MainInputFilename and OutputFilename are pulled from the FrontendOptions, while Triple is parsed directly from the ArgList.
Eventually, MainInputFilename and OutputFilename should likely be removed from IRGenOptions, in favor of the values in FrontendOptions, while Triple will be in a separate TargetOptions class.

b0092c4717 [frontend] Initial support for performing non-EmitObject actions in the integrated frontend.

  - Parse
  - DumpParse
  - DumpAST
  - PrintAST
  - EmitSILGen
  - EmitSIL
  - EmitIR
  - EmitBC
  - EmitAssembly
  - EmitObject

Moved the code for compiling into a separate performCompile() function in frontend_main.cpp, to facilitate using early returns while still supporting the diagnostic verifier.
Added some error output for the REPL, Immediate, and EmitModuleOnly actions, as the integrated frontend does not yet support these actions.

- Added support for invoking the Swift frontend via "swift_driver -frontend".
- Added frontend_main.cpp, which implements the main entry point for the

  into an object file.)
- Removed lib/Frontend/FrontendOptions.td, and replaced its functionality with
  options in include/Swift/Driver/Options.td and a new
  include/Swift/Driver/FrontendOptions.td. Options supported by the frontend
  are denoted by the FrontendOption flag; options which are not supported by
  the driver are denoted by the NoDriverOption flag.
- Updated CompilerInvocation::parseArgs() to use the option table returned from
  createDriverOptTable(), including renaming a handful of options. (-triple is
  now -target, and -Xclang is now -Xcc.)
