These tests pass with Windows 7 x64 + MSYS2. I'll see if the bots like
them as well and disable the failing ones.

Summary: I somehow forgot to add these when I added the basic floating-point opcodes. Also remove ceil/floor/trunc/nearestint for now, and add them only when properly tested.

This adds somewhat basic preparation functionality including:
- Formation of funclets via coloring basic blocks.
- Cloning of polychromatic blocks to ensure that funclets have unique
program counters.
- Demotion of values used between different funclets.
- Some amount of cleanup once we have removed predecessors from basic
blocks.
- Verification that we are left with a CFG that makes some amount of
sense.
N.B. Arguments and numbering still need to be done.

This patch and a relatec clang patch solve the problem of having to explicitly enable analysis when specifying a loop hint pragma to get the diagnostics. Passing AlwasyPrint as the pass name (see below) causes the front-end to print the diagnostic if the user has specified '-Rpass-analysis' without an '=<target-pass>’. Users of loop hints can pass that compiler option without having to specify the pass and they will get diagnostics for only those loops with loop hints.

This commit serializes the UsedPhysRegMask register mask from the machine
register information class. The mask is serialized as an inverted
'calleeSavedRegisters' mask to keep the output minimal.
This commit also allows the MIR parser to infer this mask from the register
mask operands if the machine function doesn't specify it.

This patch moves checking the threshold of runtime pointer checks to the vectorization requirements (late diagnostics) and emits a diagnostic that infroms the user the loop would be vectorized if not for exceeding the pointer-check threshold. Clang will also append the options that can be used to allow vectorization.

Summary:
For now output using C99's hexadecimal floating-point representation.
This patch also cleans up how machine operands are printed: instead of special-casing per type of machine instruction, the code now handles operands generically.

The PATCHPOINT instructions have a single optional defined register operand,
but the machine verifier can't verify the optional defined register operands.
This commit makes sure that the machine verifier won't report an error when a
PATCHPOINT instruction doesn't have its optional defined register operand.
This change will allow us to enable the machine verifier for the code
generation tests for the patchpoint intrinsics.

Summary:
This makes it so that reports symbolized after the fact with
llvm-symbolizer are more similar to the ones we generate at runtime with
in-process dbghelp.

With this we finally have an ELFFile that is O(1) to construct. This is helpful
for programs like lld which have to do their own section walk.

frame setup instruction.
This commit ensures that the stack map lowering code in FastISel adds an
appropriate number of immediate operands to the frame setup instruction.
The previous code added just one immediate operand, which was fine for a target
like AArch64, but on X86 the ADJCALLSTACKDOWN64 instruction needs two explicit
operands. This caused the machine verifier to report an error when the old code
added just one.

NaCl's sandbox doesn't allow PUSHF/POPF out of security concerns (priviledged emulators have forgotten to mask system bits in the past, and EFLAGS's DF bit is a constant source of hilarity). Commit r220529 fixed PR20376 by saving cmpxchg's flags result using EFLAGS, this commit now generated LAHF/SAHF instead, for all of x86 (not just NaCl) because it leads to an overall performance gain over PUSHF/POPF.
As with the previous patch this code generation is pretty bad because it occurs very later, after register allocation, and in many cases it rematerializes flags which were already available (e.g. already in a register through SETE). Fortunately it's somewhat rare that this code needs to fire.
I did [[ https://github.com/jfbastien/benchmark-x86-flags | a bit of benchmarking ]], the results on an Intel Haswell E5-2690 CPU at 2.9GHz are:

Clearly `PUSHF`/`POPF` are suboptimal. It doesn't really seems to be worth teaching LLVM about individual flags, at least not for this purpose.
