For various reasons, it can be useful/interesting to create builds of
Swift that minimize dependencies. Let's try to keep that working as long
as we can.
The frontend supports this via new options -index-unit-output-path and
-index-unit-output-path-filelist that mirror -o and -output-filelist. These are
intended to allow sharing index data across builds in separate directories (so
different -o values) that are otherwise equivalent as far as the index data is
concerned (e.g. an ASAN build and a non-ASAN build) by supplying the same
-index-unit-output-path for both.
This change updates the driver to add these new options to the frontend
invocation 1) when a new "index-unit-output-path" entry is specified for one
or more input files in the -output-file-map json or 2) if -index-file is
specified, when a new -index-unit-output-path driver option is passed.

These new options mirror -o and -output-filelist and are used instead
of those options to supply the output file path(s) to record in the
index store. This is intended to allow sharing index data across
builds in separate directories that are otherwise equivalent as far
as the index data is concered (e.g. an ASAN build and a non-ASAN build)
by supplying the same -index-unit-output-path for both.

Build swift-frontend as the primary Swift binary, and have
swift/swiftc/etc. symlink over to it. This is a step toward allowing
swift-driver to replace the swift and swiftc binaries.
c-index-test sorts the units by their file name, which for the modules in
in this test is just [target-triple].swiftinterface-[hash-of-full-output-path]
and so changes depending on where it's run.
Several tests related to indexing system modules were taking a considerable
amount of time (100+ seconds in the worst case) indexing the standard library.
This adds a frontend option to skip it and updates those tests to pass it.
It was hard-coding IsStatic to false rather than passing it through from the
VarDecl, giving the same USR for the two getters in the below:
class FixtureClass95 {
private static var someVar: String!
private var someVar: String!
}

Clang 8 or 9 seems to have changed from EXE to exe. Allow both
capitalizations (which is not important in Windows) as a workaround.
Maybe in the future we can remove the uppercase option.
...a situation we get into with indexing. The way Xcode generates
indexing invocations is to take a build command and add additional
flags to it; in order for the Driver to produce a single frontend
command from /that/, it currently plans as if it's going to do a
whole-module -typecheck and then turns around and uses -primary-file
anyway. This is questionable practice, to be sure...
...but meanwhile, let's not crash by trying to access declarations
that haven't been type-checked yet.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances in the swift repo.
`chmod -w` really doesn't make sense on Windows. Although NTFS allows
for readonly directories, it is something done through file system level
ACLs. This test doesn't really apply to Windows.
This changes the Swift resource directory from looking like
lib/
swift/
macosx/
libswiftCore.dylib
libswiftDarwin.dylib
x86_64/
Swift.swiftmodule
Swift.swiftdoc
Darwin.swiftmodule
Darwin.swiftdoc
to
lib/
swift/
macosx/
libswiftCore.dylib
libswiftDarwin.dylib
Swift.swiftmodule/
x86_64.swiftmodule
x86_64.swiftdoc
Darwin.swiftmodule/
x86_64.swiftmodule
x86_64.swiftdoc
matching the layout we use for multi-architecture swiftmodules
everywhere else (particularly frameworks).
There's no change in this commit to how Linux swiftmodules are
packaged. There's been past interest in going the /opposite/ direction
for Linux, since there's not standard support for fat
(multi-architecture) .so libraries. Moving the .so search path /down/
to an architecture-specific directory on Linux would allow the same
resource directory to be used for both host-compiling and
cross-compiling.

Module references get indexed as a 'module' symbol; they get USRs similar to how clang would assign a USR for a module reference.

This makes the tests more focused on what they are interested in testing
and allows flexibility on changing dependency printing on the clang side
without breaking the swift tests.
Index-while-building ends up querying some conformances that aren’t
strictly needed by the type-checker, but which require us to pre-check all
conformances for any extension we have. Long-term, this is wasted effort, but
for now it eliminates a recent regression caused by the request-evaluator,
which (intentionally) tries to perform less work for non-primary files.
Fixes rdar://problem/41392714.
When the supplementary-outputs file is written for an -index-file invocation it writes out the first input file
given in arguments instead of the input file that is provided by -index-file-path option. This then causes the frontend
index invocation to fail with an error because there is a mismatch in the primary input file and the input file that is written
in the supplementary-outputs file.
This converts the instances of the pattern for which we have a proper
substitution in lit. This will make it easier to replace it
appropriately with Windows equivalents.
- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.
Don't bail on dups.
