4fa7e54329 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the 
moment, that I will need to make far-reaching changes.

7efbe6a243 Use find instead of operator[] to test whether an element is in a std::map. 
This fixes a bug that caused -debug-pass=Details to abort.

cbd3f64f54 --- Reverse-merging (from foreign repository) r74648 into '.': 
U    include/llvm/LLVMContext.h
U    lib/VMCore/LLVMContext.cpp
U    lib/AsmParser/LLParser.cpp
U    lib/AsmParser/LLParser.h

Temporarily reverting r74648. It was causing massive failures in release mode.

29ea777c1e Add a portable strerror*() wrapper, llvm::sys::StrError(). This includes the 
Windows variant, strerror_s, but I couldn't test that.

I'll update configure and config.h.in in a subsequent patch.

fbe8d883a0 I give up on trying to use reader/writer locks for recursive type refinement. Use a recursive mutex instead, which will (in theory) generate more contention, but is really 
a much more natural fit for what's going on during recursive type refinement.

81b8dabb53 Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

e6989735a6 CommuteChangesDestination() should check if to-be-commuted instruction defines any register. Also teaches the default commuteInstruction() to commute instruction without definitions (e.g. X86::test / ARM::tsp).

7d78cb531e Remove special handling of implicit_def. Fix a couple more bugs in liveintervalanalysis and coalescer handling of implicit_def. 
Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def.

37503e9671 Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details.

bc3d149e98 Remove unused AsmPrinter OptLevel argument, and propogate. 
- This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

c0fb316bd3 Add an "alignment" field to the MachineFunction object. It makes more sense to 
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

This allows for future work that would allow for precise no-op placement and the
like.

340632e814 Fix PR4485. 
Avoid unnecessary duplication of operand 0 of X86::FpSET_ST0_80. This duplication would
cause one register to remain on the stack at the function return.

28b9e77f19 Temporarily restore the scavenger implicit_def checking code. MachineOperand isUndef mark is not being put on implicit_def of physical registers (created for parameter passing, etc.).

c6c942b70f Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them. 
The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.

This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.
