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.

Adrian Prantl a763447124 Implement a new -fstandalone-debug option. rdar://problem/15685848
It controls everything that -flimit-debug-info used to, plus the
vtable type optimization. The old -fno-limit-debug-info option is now an
alias to -fstandalone-debug and vice versa.

Standalone is the default on Darwin until dtrace is updated to work with
non-standalone debug info (rdar://problem/15758808).

Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
because NoStandaloneDebugInfo sounded even more confusing.

David Blaikie 86eac722f9 Simplify/generalize some debug info test cases
Mostly, try to depend on the annotation comments more so these tests are more
legible, brief, and agnostic to schema changes in the future (sure, they're not
agnostic to changes to the comment annotations but since they're easier to read
they should be easier to update if that happens).

David Blaikie f85744235b Generalize DebugInfo tests by avoiding explicit metadata numbers
This addresses several (not all) debug info tests that use explicit metadata
numbers. Wherever the same number appeared more than once in a test I used
a named match to ensure the same number appeared in all those cases (this may
still be overly constraining test cases as they may not have actually cared
about that relationship). For one-off numbers I just replaced them with an
unnamed regex.

This may underconstrain poorly written test cases that were interested in
checking that certain metadata nodes were related but didn't actually match
on all the related nodes numbers.

Eric Christopher 1c3785aae9 Add in a caching mechanism so that forward declarations are replaced
with full types if they exist.

Eric Christopher 4c006e557d Reapply r150631:
"Add a completed/incomplete type difference. This allows us to have
    partial types for contexts and forward decls while allowing us to
    complete types later on for debug purposes.

    This piggy-backs on the metadata replacement and rauw changes
    for temporary nodes and takes advantage of the incremental
    support I added in earlier. This allows us to, if we decide,
    to limit adding methods and variables to structures in order
    to limit the amount of debug information output into a .o file.

    The caching is a bit complicated though so any thoughts on
    untangling that are welcome."

with a fix:

 - Remove all RAUW during type construction by adding stub versions
   of types that we later complete.

and some TODOs:

 - Add an RAUW cache for forward declared types so that we can replace
   them at the end of compilation.
 - Remove the code that updates on completed types because we no
   longer need to have that happen. We emit incomplete types on
   purpose and only want to know when we want to complete them.
