Douglas Katzman 3459ce2e5e Stop messing with the 'g' group of options in CompilerInvocation.
With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.

Also fix a bug in the Windows compatibility argument parsing
in which the "rightmost argument wins" principle failed.

Duncan P. N. Exon Smith 9dd4e4e63a DebugInfo: Metadata constructs now start with DI*
LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now
that the `DIDescriptor` hierarchy has been gone for about a week.  This
commit was generated using the rename-md-di-nodes.sh upgrade script
attached to PR23080, followed by running clang-format-diff.py on the
`lib/` portion of the patch.

Ben Langmuir bc35fbe43a Don't try to rebuild modules on umbrella header mismatch
There are two issues here:
1) It's too late to rebuild at this point, because we won't go through
removeModules and when we try to reload the new .pcm we'll get the old
one instead.  We might be able to call removeModules after an OutOfDate
here, but I'm not yet confident that it is always safe to do so.

2) In practice, this check fails spuriously when the umbrella header
appears to change because of a VFS change that means it maps to a
different copy of the same file.  Because of this, we just skip the
check for now.

This reverts commit r218917, effectively reapplying r218913.  Original
commit message follows.

Update debug info testcases for an LLVM metadata schema change to fold
metadata constant operands into a single `MDString`.

Ben Langmuir 54cbc706b1 Make -Wincomplete-umbrella go through the VFS
By using vfs::recursive_directory_iterator, this warning will now fire
when some or all of a module's headers are from VFS mappings.

Ben Langmuir 5de00f3b56 Stopgap fix for finding module for a file mapped in the VFS
If we lookup a path using its 'real' path first, we need to ensure that
when we run header search we still use the VFS-mapped path or we will
not be able to find the corresponding module for the header.

The real problem is that we tie the name of a file to its underlying
FileEntry, which is uniqued by inode, so we only ever get the first name
it is looked up by. This doesn't work with modules, which rely on a
specific file system structure.  I'm hoping to have time to write up a
proposal for fixing this more permanently soon, but as a stopgap this
patch updates the name of the file's directory if it comes from a VFS
mapping.

Ben Langmuir 2c9af44c26 When module umbrellas change, rebuild them
With the VFS, it is easy to hit modified umbrellas by overriding the
umbrella header, and what we want is to rebuild, not to fail.

Ben Langmuir f9a6ac213a Add a test where the module map is overriden in the vfs
Specifically, we pass two -ivfsoverlay yaml files, and the topmost one
remaps the module map file.

Ben Langmuir a6f8ca8c5f Support relative paths in VFSFromYAML
Use llvm::sys::fs::make_absolute to get an absolute path before
matching. Also, allow "." directories to enable testing.  ".." is still
not supported, and will require crossing file system boundaries to
implement correctly.

Ben Langmuir d066d4c849 Reapply fixed "Honour 'use-external-names' in FileManager"
Was r202442

There were two issues with the original patch that have now been fixed.
1. We were memset'ing over a FileEntry in a test case. After adding a
   std::string to FileEntry, this still happened to not break for me.
2. I didn't pass the FileManager into the new compiler instance in
   compileModule. This was hidden in some cases by the fact I didn't
   clear the module cache in the test.

Also, I changed the copy constructor for FileEntry, which was memcpy'ing
in a (now) unsafe way.
