This is a testcase for r209227, a change in LLVM that automatically sets
visibility to default when the linkage is changed to local (rather than
asserting).

What this testcase triggers is hard to reproduce otherwise:  the
`GlobalValue` is created (with non-local linkage), the visibility is set
to hidden, and then the linkage is set to local.

This is a GNU attribute that causes calls within the attributed function
to be inlined where possible. It is implemented by giving such calls the
alwaysinline attribute.

None of these attributes require FunctionTemplate to be explicitly listed as part of their subject definition. FunctionTemplateDecls are not what the attribute appertains to in the first place -- it attaches to the underlying FunctionDecl.

The attribute emitter was using FunctionTemplate to map the diagnostic to "functions or methods", but that isn't a particularly clear diagnostic in these cases anyway (since they do not apply to ObjC methods). Updated the attribute emitter to remove custom logic for FunctionTemplateDecl, and updated the test cases for the change in diagnostic wording.

It appears that Windows doesn't like renaming over open files, which we
do in clearOutputFiles. The file being compiled should be safe to
removed, but this isn't very satisfying - we don't want to manually
manage the lifetime of files we cannot prove have no references.

The -no-ns-alloc-error migration option now causes the diagnostic to be ignored
completely. If this isn't desired, the error can be downgraded to a warning
using the usual -Wno-error=arcmt-ns-alloc.

Note that we can't use -verify right now on this test because
VerifyDiagnosticConsumer gets confused by multiple SourceManager instances,
which is presumably the reason it was XFAILed in the first place and why the
regression wasn't detected. We'll grep instead for now.

This patch implements global named registers in Clang, lowering to the just
created intrinsics in LLVM (@llvm.read/write_register). A new type of LValue
had to be created (Register), which just adds support to carry the metadata
node containing the name of the register. Two new methods to emit loads and
stores interoperate with another to emit the named metadata node.

No guarantees are being made and only non-allocatable global variable named
registers are being supported. Local named register support is unchanged.

Follow-up fix for 209138.  Actually, since we already have this file
open, we don't want to refresh the stat() info, since that might be
newer than what we have open (bad!).

FileManager::invalidateCache is not safe to call when there may be
existing references to the file. What module load failure needs is
to refresh so stale stat() info isn't stored.

This may be the last user of invalidateCache; I'll take a look and
remove it if possible in a future commit.

This caused a use-after-free error as well as a spurious error message
that a module was "found in both 'X.pcm' and 'X.pcm'" in some cases.

This test is XFAILed on Windows, but I cannot see a reason as to why it should be failing. The original commit which XFAILed this was r111581, which suggested something was wrong with file remapping, but that may have been subsequently fixed.

Removing the XFAIL, but will watch the build bots to see if any go red because of this. Local testing on Windows succeeds.
