1) Make sure we emit static member variables by checking
at the end of createGlobalVariableDIE rather than piecemeal
in the function.
(As a note, createGlobalVariableDIE needs rewriting.)

2) Make sure we use the definition rather than declaration DIE
for two things: a) determining linkage for gnu pubnames, and b)
as the address of the DIE for global variables.
(As a note, createGlobalVariableDIE really needs rewriting.)

Adjust the testcase to make sure we're checking the correct DIEs.

Because of win32 mangling, we produce symbol and section names with
funny characters in them, most notably @ characters.

MC would choke on trying to parse its own assembly output. This patch addresses
that by:

- Making @ trigger quoting of symbol names
- Also quote section names in the same way
- Just parse section names like other identifiers (to allow for quotes)
- Don't assume @ signifies a symbol variant if it is in a string.

This changes the SelectionDAG scheduling preference to source
order. Soon, the SelectionDAG scheduler can be bypassed saving
a nice chunk of compile time.

Performance differences that result from this change are often a
consequence of register coalescing. The register coalescer is far from
perfect. Bugs can be filed for deficiencies.

On x86 SandyBridge/Haswell, the source order schedule is often
preserved, particularly for small blocks.

Register pressure is generally improved over the SD scheduler's ILP
mode. However, we are still able to handle large blocks that require
latency hiding, unlike the SD scheduler's BURR mode. MI scheduler also
attempts to discover the critical path in single-block loops and
adjust heuristics accordingly.

The MI scheduler relies on the new machine model. This is currently
unimplemented for AVX, so we may not be generating the best code yet.

Unit tests are updated so they don't depend on SD scheduling heuristics.

Some background: One can pass compiled resource files (.res files) directly
to the linker on Windows. If a resource file is given, the linker will run
"cvtres" command in background to convert the resource file to a COFF file
to link it.

What I'm trying to do with this patch is to make the linker to recognize
the resource file by file magic, so that it can run cvtres command.

Extend DummySyntheticProvider to actually use debug-info vended children as the source of information
Make Python synthetic children either be valid, or fallback to the dummy, like their C++ counterparts

+ 80 cols fix.

llvm-svn: 192728

If unqualified id lookup fails while parsing a class template with a
dependent base, clang with -fms-compatibility will pretend the user
prefixed the name with 'this->' in order to delay the lookup.  However,
if there was a unary ampersand, Sema::ActOnDependentIdExpression() will
create a DependentDeclRefExpr, which is not what we wanted at all.  Fix
this by building the CXXDependentScopeMemberExpr directly instead.

In order to be fully MSVC compatible, we would have to defer all
attempts at name lookup to instantiation time.  However, until we have
real problems with system headers that can't be parsed, we'll put off
implementing that.

Fixes PR16014.

- Type of index used in extract_vector_elt or insert_vector_elt supposes
  to be TLI.getVectorIdxTy() which is pointer type on most targets. It'd
  better to truncate (or zero-extend in case it's changed later) it to
  mask element type to guarantee they are matching instead of asserting
  that.

- Lower signed division by constant powers-of-2 to target-independent
  DAG operators instead of target-dependent ones to support them better
  on targets where vector types are legal but shift operators on that
  types are illegal. E.g., on AVX, PSRAW is only available on <8 x i16>
  though <16 x i16> is a legal type.
