Mixed-source targets generally include the generated <Product>-Swift.h
header in many Objective-C (.m) source files. Any change to a Swift file
results in the header being touched, which means all the .m files get
recompiled.
This change makes Swift write the generated header to a temporary file
first, then use the previous commit's moveFileIfDifferent to put it in
its final destination.

... with disabled test 1_stdlib/Bit.swift for ios.
Most likely the problem of 1_stdlib/Bit.swift (only on armv7) is just uncovered by this change.
Unfortunately I have no possibility to debug the problem on a device. Therefore I filed rdar://problem/20521110

This avoids that an unoptimized imported function is linked instead the optimized version from the stdlib.

It gives considerable performance improvmenets for some benchmarks with -Onone. E.g.
PopFrontUnsafePointer: +281%
ArrayOfPOD: +92%
StrComplexWalk: +91%
ArrayOfGenericPOD: +61%
Several others are within the range of +10% to +30%.
For the implementation I added runSILPassesForOnone() in Passes.cpp.
Here we can add other optimizations for -Onone in the future.

These should all apply to any Darwin platform, and the current behaviour
was breaking cross-compilation.
Introduces a SWIFT_DARWIN_VARIANTS pattern, to be used as follows:
if(SWIFT_HOST_VARIANT MATCHES "${SWIFT_DARWIN_VARIANTS}")
Also fix one place where I checked the CMAKE_SYSTEM_NAME instead of the
host variant that I recently introduced. I haven't attempted to find
the rest of the places we're doing this though.

Currently a no-op, but effective access for entities within the current
module will soon need to take testability into account. This declaration:
internal func foo() {}
has a formal access of 'internal', but an effective access of 'public' if
we're in a testable mode.

- Add frontend and standard library build support for tvOS.
- Add frontend support for watchOS.
watchOS standard library builds are still disabled during SDK bring-up.
To build for TVOS, specify --tvos to build-script.
To build for watchOS, specify --watchos to build-script (not yet supported).
This patch does not include turning on full tests for TVOS or watchOS, and
will be included in a follow-up patch.

This will be needed for split-llvm code generation.
If multiple -o options are specified and only a single output file is needed
(currently always), the last one wins. This is NFC.

Move helper function EmbedBitcode() from frontend_main.cpp to IRGen.cpp so we

...so that the debugger has the best possible chance of being able to load
the app properly.
We don't do this for frameworks today because we don't want to leak this
information into the public module; once we have a distinction between
"the module that ships with the framework" and "the module that goes into
the debug info" we can do this for frameworks as well.

Yes, they may not be correct, but the stale ones that were there before
won't be correct either (if they were there at all). This should make both
Xcode and the Swift driver less likely to have issues when there's an error
in a newly added file.

This adds support to build-script and cmake scripts for cross-compiling the host tools in addition to stdlib.
To cross-compile, build-script-impl now accepts --cross-compile-tools-deployment-targets with a space separated list of targets to cross compile host Swift tools for.
For example: $ build-script ...other-args... -- --cross-compile-tools-deployment-targets="iphoneos-arm64 iphoneos-armv7".
When installing cross-compiled tools, it now also merges and runs lipo to produce fat binaries by merging the cross-compiled target architectures.

There's also a testing option, -serialize-debugging-options, to force this
extra info to be serialized even for library targets. In the long run we'll
probably write out this information for all targets, but strip it out of
the "public module" when a framework is built. (That way it ends up in the
debug info's copy of the module.)
Incidentally, this commit includes the ability to add search paths to the
Clang importer on the fly, which is most of rdar://problem/16347147.
Unfortunately there's no centralized way to add search paths to both Clang
/and/ Swift at the moment.

PrintAsObjC behaves slightly differently in apps vs. frameworks: for apps,
you get internal decls exposed in the header as well as public ones. This
is because the generated header is not being shipped anywhere and thus we
don't have a secrecy leak.
However, we were detecting whether we were in an app based on whether or
not we had a bridging header. That's no good for mixed-source apps where
there's no bridging header, so now we also check for a main entry point,
whether generated from @UIApplicationMain or @NSApplicationMain, or from
a script source file (main.swift).

This has been long in coming. We always had it in IRGenOpts (in string form).
We had the version number in LangOpts for availability purposes. We had to
pass IRGenOpts to the ClangImporter to actually create the right target.
Some of our semantic checks tested the current OS by looking at the "os"
target configuration! And we're about to need to serialize the target for
debugging purposes.

Changing the design of this to maintain more local context

Locally scoped type declarations were previously not serialized into the
module, which meant that the debugger couldn't reason about the
structure of instances of those types.
Introduce a new mangling for local types:
[file basename MD5][counter][identifier]
This allows the demangle node's data to be used directly for lookup
without having to backtrack in the debugger.
Local decls are now serialized into a LOCAL_TYPE_DECLS table in the
module, which acts as the backing hash table for looking up
[file basename MD5][counter][identifier] -> DeclID mappings.
New tests:
* swift-ide-test mode for testing the demangle/lookup/mangle lifecycle
of a module that contains local decls
* mangling
* module merging with local decls

These are the same dependencies collected for .d files, including

This refactoring is groundwork for saving the cross-module dependencies
in the swiftdeps files as well, so that we know to rebuild files if an
outside file changes (such as a bridging header, another framework's
headers, or another framework's swiftmodule).

This flag enables one to specify a json file that expresses a specific
pipeline in the following format:
[
[
"$PASS_MANAGER_ID",
"run_n_times"|"run_to_fixed_point",
$NUM_ITERATIONS,
"$PASS1", "$PASS2", ...
],
...
]
This will make it easier to experiment with different pass pipelines by
allowing:
1. Automatic generation of pass pipelines without needing to recompile
the compiler itself.
2. Simple scripting of pass pipelines via the json meta language.
3. Enabling the easy expression and reproducability of a specific
pipeline ordering via radar.
In the next commit I will provide a python library for the generation of these
json files with a few types of pipeline generators already created.
