John McCall 644a4181c9 Implement -Wsign-compare, or at least the actual comparison part of it. 
Conditional operands are next.

Fixes part of rdar://problem/7289584.

Victor Hernandez 492ed30a32 Update CreateMalloc so that its callers specify the size to allocate: 
MallocInst-autoupgrade users use non-TargetData-computed allocation sizes.
Optimization uses use TargetData to compute the allocation size.

Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays.
Extend getMallocType() to support malloc calls that have non-bitcast uses.

Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use.

Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes.

Douglas Gregor 41127188ac When starting a C++ member access expression, make sure to compute the 
type of the object even when it is dependent. Specifically, this makes
sure that we get the right type for "this->", which is important when
performing name lookup into this scope to determine whether an
identifier or operator-function-id is a template name.

Jim Grosbach cc58cc1d56 dynamic stack realignment necessitates scanning the floating point callee-

Jakob Stoklund Olesen c7cfc94bcc Print out an informative comment for KILL instructions. 
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

Evan Cheng 95bdc5d899 RangeIsDefinedByCopyFromReg() should check for subreg_to_reg, insert_subreg, 
and extract_subreg as a "copy" that defines a valno.

happening before.

Chris Lattner cb3c64ee3c move two functions up higher in the file. Delete a useless argument 
to EmitGEPOffset.  

Implement some new transforms for optimizing 
subtracts of two pointer to ints into the same vector.  This happens
for C++ iterator idioms for example, stringmap takes a const char*
that points to the start and end of a string.  Once inlined, we want
the pointer difference to turn back into a length.

This is rdar://7362831.
