Jim Grosbach 9fa0481569 Disable InstCombine unsafe folding bitcasts of calls w/ varargs. 
Changing arguments from being passed as fixed to varargs is unsafe, as
the ABI may require they be handled differently (stack vs. register, for
example).

Remove two tests which rely on the bitcast being folded into the direct
call, which is exactly the transformation that's unsafe.

Kevin Enderby e1a12cf3ee Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses a 
symbol from an assignment.  In this case the symbol did not have a fragment so
MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.

Bob Wilson aa30aff4f7 Add Triple::getMacOSXVersion to replace crufty code in the clang driver. 
This new function provides a way to get the Mac OS X version number from
either generic "darwin" triples of macosx triples.

Jakob Stoklund Olesen f1bb151917 Add a TableGen CodeGenSubRegIndex class. 
This class is used to represent SubRegIndex instances instead of the raw
Record pointers that were used before.

Manuel Klimek 31becd7c88 RefCountedBaseVPTR needs the IntrusiveRefCntPtrInfo as friend, 
now that this handles the release / retain calls.

Adds a regression test for that bug (which is a compile-time
regression) and for the last two changes to the IntrusiveRefCntPtr,
especially tests for the memory leak due to copy construction of the
ref-counted object and ensuring that the traits are used for release /
retain calls.

Andrew Trick 2b3c187489 RAFast: Generalize the logic for return operands. 
This removes implicit assumption about the form of MI coming into regalloc. In particular, it should be independent of ProcessImplicitDefs which will eventually become a standard part of coming out of SSA--unless we simply can eliminate IMPLICIT_DEF completely. Current unit tests expose this once I remove incidental pass ordering restrictions.

This is not a final fix. Just a temporary workaround until I figure out the right way.

Chris Lattner 8193b06e44 start moving SimplifyLibcalls over to getConstantStringInfo, which is 
dramatically more efficient than GetConstantStringInfo.

Chris Lattner 108423a94a Change ConstantArray::get to form a ConstantDataArray when possible, 
kicking in the big win of ConstantDataArray.  As part of this, change
the implementation of GetConstantStringInfo in ValueTracking to work
with ConstantDataArray (and not ConstantArray) making it dramatically,
amazingly, more efficient in the process and renaming it to 
getConstantStringInfo.

This keeps around a GetConstantStringInfo entrypoint that (grossly)
forwards to getConstantStringInfo and constructs the std::string 
required, but existing clients should move over to 
getConstantStringInfo instead.
