This patch adds a new Clang compiler flag "-gline-tables-only".
It reduces the amount of emitted debug information:
1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram,
DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only.
2) .debug_str contains only function names.
3) No debug data for types/namespaces/variables is emitted.
4) The data in .debug_line is enough to produce valid stack traces with
function names and line numbers.

Fix handling of wint_t - we can't assume wint_t is purely an integer promotion of wchar_t - they may differ in signedness.

Teach ASTContext about WIntType, and have it taken from TargetInfo like WCharType. Should fix test/Sema/format-strings.c for ARM, with the exception of one subtest which will fail if wint_t and wchar_t are the same size and wint_t is signed, wchar_t is unsigned.

There'll be a followup commit to fix that.

Add a predefine __WINT_UNSIGNED__, similar to __WCHAR_UNSIGNED__, and test them both for ARM and X86.

Use this to fully fix Sema/format-strings.c for non-x86 platforms.

Move Sema::RequireCompleteType() and Sema::RequireCompleteExprType()
off PartialDiagnostic. PartialDiagnostic is rather heavyweight for
something that is in the critical path and is rarely used. So, switch
over to an abstract-class-based callback mechanism that delays most of
the work until a diagnostic is actually produced. Good for ~11k code
size reduction in the compiler and 1% speedup in -fsyntax-only on the
code in <rdar://problem/11004361>.

IsTailPaddedMemberArray uses a FieldDecl's
getTypeSourceInfo() without checking for NULL.
FieldDecls may have NULL TypeSourceInfo, and in
fact some FieldDecls generated by Clang -- and
all FieldDecls generated by LLDB -- have no
TypeSourceInfo.

This patch makes IsTailPaddedMemberArray check
for NULL.

Synchronize the representations of DeclarationName and Selector so
that bridging between the two is free. Saves ~4k of code size,
although I don't see any measurable performance difference
(unfortunately).
