Douglas Gregor 55b037b9f3 During code completion, give the "nil" and "NULL" macros the same 
priority as other constants. And, if we're in a place where we prefer
a pointer type, consider "nil" and "NULL" to be close matches.

Kevin Enderby ea9207cd7a Revert some unneeded parts of the change in r107886 for the 
.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

Jakob Stoklund Olesen 63a622b768 Teach the x86 floating point stackifier to handle COPY instructions. 
This pass runs before COPY instructions are passed to copyPhysReg, so we simply
translate COPY to the proper pseudo instruction. Note that copyPhysReg does not
handle floating point stack copies.

Once COPY is used everywhere, this can be cleaned up a bit, and most of the
pseudo instructions can be removed.

Jakob Stoklund Olesen 00264624a9 Convert EXTRACT_SUBREG to COPY when emitting machine instrs. 
EXTRACT_SUBREG no longer appears as a machine instruction. Use COPY instead.

Add isCopy() checks in many places using isMoveInstr() and isExtractSubreg().
The isMoveInstr hook will be removed later.

Argyrios Kyrtzidis a4ed18191c For TagType and TemplateSpecializationType, isDependent calculation may be invalid because some decls that the 
calculation is using may still be initializing.

Benjamin Kramer 2321e6a4d4 Teach instcombine to transform 
(X >s -1) ? C1 : C2 and (X <s  0) ? C2 : C1
into ((X >>s 31) & (C2 - C1)) + C1, avoiding the conditional.

This optimization could be extended to take non-const C1 and C2 but we better
stay conservative to avoid code size bloat for now.

for
int sel(int n) {
     return n >= 0 ? 60 : 100;
}

we now generate
  sarl  $31, %edi
  andl  $40, %edi
  leal  60(%rdi), %eax

instead of
  testl %edi, %edi
  movl  $60, %ecx
  movl  $100, %eax
  cmovnsl %ecx, %eax

Chandler Carruth e51a119fc6 Wrap the new ext-warn on extraneous comma on the last entry of an enumerator 
list in a diagnostic group so it can be turned on and off. A terrifying amount
of code, including large chunks of open source code, still do this so it's
important to be able to suppress it when necessary.

Doug, is this a reasonable compromise? I'd lean toward making it a normal
extension, but I don't feel strongly as long as we can turn the warnings off.

Chandler Carruth dd1bc0f1b5 Add support for differentiating between attributes ignored when handled and 
unknown attributes that we discard. Add a diagnostic group for unknown
attribute warnings to allow turning these off when we don't care. Also
