69ad27c7e3 Reg Scavenging generalization (Thumb support): 
- start support for new PEI w/reg alloc, allow running RS from emit{Pro,Epi}logue() target hooks.
- fix minor issue with recursion detection.

e94b3f7a34 Add assertion checks after the calls to LowerFormalArguments, LowerCall, 
and LowerReturn, to verify that the targets' hooks have respected some
of their postconditions.

904eb68a6a Remove an over-aggressive assert. Functions with empty struct return 
types don't have any return values, from CodeGen's perspective.
This fixes PR4688.

668a0ff5ef Fix a bug in x86's PreprocessForRMW logic that was exposed 
by aggressive chain operand optimization. UpdateNodeOperands
does not modify the node in place if it would result in
a node identical to an existing node.

01b8a3593b Fix a few places in DAGCombiner that were creating all-ones-bits 
and high-bits values in ways that weren't correct for integer
types wider than 64 bits. This fixes a miscompile in
PPMacroExpansion.cpp in clang on x86-64.

905678ab37 Neon does not actually have VLD{234}.64 instructions.

6ee52e0047 Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.

6e4065d7c6 When using NEON for single-precision FP, the NEON result must be placed in D0-D15 as these are the only D registers with S subregs. Introduce a new regclass to represent D0-D15 and use it in the NEON single-precision FP patterns.

ba72f59923 Fix FindExecutable to use sys::Path::GetMainExecutable instead of 
just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.

Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.
