This was causing all the external definitions to go from SILGen through
IRGen multiple times per REPL statement. Since this only matters if we
have source modules enabled, just turn it off.
We still generate all the external definitions for every REPL /line/, which
is the cause of <rdar://problem/16164076>.

outside of debugger-support mode. Rip out the existing special-case
code when parsing expr-identifier.
This means that the Lexer needs a LangOptions. Doug and I
talked about just adding that as a field of SourceMgr, but
decided that it was worth it to preserve the possibility of
parsing different dialects in different source files.
By design, the lexer doesn't tokenize fundamentally differently
in different language modes; it might decide something is invalid,
or it might (eventually) use a different token kind for the
same consumed text, but we don't want it deciding to consume more or
less of the stream per token.
Note that SIL mode does make that kind of difference, and that
arguably means that various APIs for tokenizing need to take a
"is SIL mode" flag, but we're getting away with it because we
just don't really care about fidelity of SIL source files.

This is equivalent to Clang's -fresource-dir; it provides the location of
compiler modules and libraries.
No end-user-visible changes, but the iOS build will no longer have to use
-I to build and test its own standard libraries.

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.

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.

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.

...since all imports are private by default, and we rely on "import Cocoa"
bringing in AppKit. (If you say "import AppKit" directly, you get an
immediate call to IRGenImportedModules, so everything works.)

1) Revert my change to give DeclContext a dump method, it confuses the debugger.
2) Refactor SILGen::requiresObjCPropertyEntryPoints out to
VarDecl::usesObjCGetterAndSetter.

In order to implement immediate and REPL modes in swift_driver, this functionality
needs to be in a library (instead of directly in the swift executable).
