MCSymbol.h shouldn't pull in MCAssembler.h, just MCFragment.h.
MCLinkerOptimizationHint.h shouldn't need MCMachObjectWriter.h. The
rest is fixing the fallout.

This is a follow-up to r273479. At the time I wrote r273479 I didn't connect the dots that the functions I was adding had to exist somewhere. Turns out, they do. This finishes moving the functions to MachO.h.
Existing MachO fat header tests like test/tools/llvm-readobj/Inputs/macho-universal-archive.x86_64.i386 execute this code.

When trying to convert a loading instruction into a FAULTING_LOAD, we
sometimes face code like this:
if %R10 is not null:
%R9<def> = MOV32ri Immediate
%R9<def, tied> = AND32rm %R9, 0x20(%R10)
else:
goto TRAP
In these cases we would like to use the AND32rm instruction as the
faulting operation by hoisting the "depedency" def-ing %R9 also above
the control flow, transforming the program into:
%R9<def> = MOV32ri Immediate
%R9<def, tied> = FAULTING_LOAD_OP(AND32rm %R9, 0x20(%R10), FailPath: TRAP)
This change teaches ImplicitNullChecks to do the above, when safe.

These routines do not require executable stacks. However, by default ELFish
linkers may assume an executable stack on GNUish environments (and some non-GNU
ones too!). The GNU extension to add a note to indicate a non-executable stack
is honoured by these environments to mark the stack as non-executable (the
compiler normally emits this directive on appropriate targets whenever
possible). This allows normal builds from getting executable stacks due to
linking to the compiler rt builtins.

Summary: Do not require __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS macros to be defined globally. They are not needed for C++11 compliant standard headers.

LLVMConfig.cmake needs to set LLVM_BINARY_DIR differently based on whether or not it is the build directory or the install directory. The build directory just needs to set the value from the configuration, the install directory needs to set it to the install prefix.

Tweak the big-types.ll test case to catch this bug. We just need an

This test is flaky. Specifically, on some Mac configurations we see the
__sanitizer_ptr_cmp as the 0th frame. Let's relax it to not require that
f is in frame #0.

This is a convenience iterator that allows clients to enumerate the
GlobalObjects within a Module.
Also start using it in a few places where it is obviously the right thing
to use.

The main sin this was committing was using terminator
instructions in the middle of the block, and then
not updating the block successors / predecessors.
Split the blocks up to avoid this and introduce new
pseudo instructions for branches taken with exec masking.
Also use a pseudo instead of emitting s_endpgm and erasing
it in the special case of a non-void return.

Transform: (store ch addr (add x (add (shl y c) e)))
to: (store ch addr (add x (shl (add y d) c))),
where e = (shl d c) for some integer d.
The purpose of this is to enable generation of loads/stores with
shifted addressing mode, i.e. mem(x+y<<#c). For that, the shift
value c must be 0, 1 or 2.

The findMIPSMultilibs is too long. One more reason for splitting is to
escape redundant calls of MultilibSet::FilterOut method which lead to

This test case checks that globals from all object files are being registered
after they've been linked together. It also checks that globals from libraries
loaded at runtime are registered.

Push a new region for the try block and propagate execution counts
through it. This ensures that catch statements get a region counter

-view-machine-block-freq-propagation-dags currently

This is similar to the computeKnownBits improvement in rL268479.
There's probably more we can do for vector logic instructions, but
this should let us see non-splat constant masking ops that can
become vector selects instead of and/andn/or sequences.

Recommiting after fixing over-aggressive assertion
[DAG] Previously debug values would transfer debuginfo for the selected
start node for a replacement which allows for debug to be dropped.
Push debug value transfer to occur with node/value replacement in
SelectionDAG, remove now extraneous transfers of debug values.
This refixes PR9817 which was being incompletely checked in the
testsuite.

CodeView needs to know if a virtual method was introduced in the current
class, and base classes may not have complete type information, so we
need to thread this bit through from the frontend.

These should be equality comparisons. Fixes assertions while
self-hosting clang with codeview debug info.
Ultimately this is going to be covered by real tests for virtual method
emission, so I'm not adding a "don't crash on this input" test that I'll
remove soon afterwards.
