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 patche and a related llvm 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.

Summary: convertToHexString doesn't represent them correctly at this point in time. This is a follow-up to sunfish's suggestion in D11914.

We will use this for ASan on Windows soon. When the ELF port of LLD
matures, we can add other sanitizer integration tests to make sure they
work with LLD.

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.

Summary:
NaCl is a platform where long double is the same as double.
Its mangling is spelled with "long double" but its ABI lowering is the same
as double.

Following one of the appended options will allow the loop to be vectorized. We do not include a command line option for modifying the pointer checking threshold because there is no clang-level interface for this currently.

A test was recently (r244468) added to cover long double calling convention
codegen, distinguishing between Android and GNU conventions (where long doubles
are fp128 and x86_fp80, respectively). Native Client is a target where long
doubles are the same as doubles. This change augments the test to cover
that case.
Also rename the test to test/codeGen/X86_64-longdouble.c

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:
A virtual base class and derived class should only poison their
respective members upon destruction. In particular, trivial members should
be poisoned directly, non-trivial members should be poisoned by their
respective destructors, and references to non-trivial members should be
poisoned.

Test case avoids casting to access members
Run configurations to reflect expected runtime failure on assertions.
Simplified access to internal members.
Updated internal member structure of base.
Revised assert in main to verify successful poisoning after dtor.
Verify address of pointer is poisoned.
Fixed assert err.
Cleaned up test by removing extraneous prints, asserts.

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.
