FYI, removed the unused MCInstrAnalysis as it does not exist for 64-bit ARM and
was causing a “couldn't initialize disassembler for target” error.

Summary:
Ok, here is somewhat addition to D6217 aiming to preserve old darwin behavior wrt the typedefed types. The actual change to SemaChecking turned out to be pretty gross, in particular:
1. We need to extract the typedef'ed type for proper diagnostics
2. We need to walk over paren expressions as well

If you have something like
__declspec(align(8192)) int foo = 1;
in your code, the compiler makes the data to be aligned to 8192-byte
boundary, and the linker align the section containing the data to 8192.
LLD always aligned the section to 4192. So, as long as alignment
requirement is smaller than 4192, it was correct, but for larger
requirements, it's wrong.
This patch fixes the issue.

We would attempt to replace a fptrunc of an frem with an identical
fptrunc. This would cause the new fptrunc to be added to the worklist.
Of course, this results in an infinite loop because we will keep
visiting the newly created fptruncs.
This fixes PR21576.

doing Load PRE"
This commit updates the failing test in
Analysis/TypeBasedAliasAnalysis/gvn-nonlocal-type-mismatch.ll
The failing test is sensitive to the order in which we process loads. This
version turns on the RPO traversal instead of the while DT traversal in GVN.
The new test code is functionally same just the order of loads that are
eliminated is swapped.
This new version also fixes an issue where GVN splits a critical edge and
potentially invalidate the RPO/DT iterator.

based on instruction complexity
The order that tablegen fast-isel instruction code is generated is
currently based on the text of the predicate (using string
less-than). This patch changes this to instead use the instruction
complexity. Because the complexities are not unique a C++ multimap is
used instead of a map.
This fixes the problem where code with no predicate always comes out
first (the empty string always compares as less than all other
strings) thus making the code with predicates dead code. See the FMUL
code in PPCFastISel.cpp for an example. It also more closely matches
the normal codegen ordering. Some error checking in the tablegen
fast-isel code is fixed as well.
Patch by Bill Seurer.

If we have spilled the value of the m0 register, then we need to restore
it with v_readlane_b32 to a regular sgpr, because v_readlane_b32 can't
write to m0.
v_readlane_b32 can't write to m0, so

This allows COFF targets to emit accelerator tables
when requested by -dwarf-accel-tables=Enable instead
of aborting. The test DebugInfo/cross-cu-inlining.ll
covers this on COFF platforms.

Effectively removes -lpthreads from linux/gcc build of test programs in test/api/multithreaded. This was done due to that combination causing a test program to hang due, likely due to an issue with gcc linker and libstdc++ conflicting pthreads code in test program and pthread used by lldb. Issue has been documented at:

ELF targets (and maybe COFF) use relocations when referring
to strings in the .debug_str section. Handle that in the
accelerator table dumper. This commit restores the
test/DebugInfo/cross-cu-inlining.ll test to its expected
platform independant form, validating that the fix works
(this test failed on linux boxes).

AddressOfEntryPoint is overridden after we layout all atoms (until then,
we don't know the entry point address for obvious reason.)
I believe this code is leftover from very early version of the
PE/COFF port that we only had an entry function in a test object file.

Summary: The strstream function `str()` sets `freeze(true)`. When `freeze` is true the destructor is not allowed to free any dynamically allocated memory. The memory leak causes ASAN to fail on these tests. To ensure memory is deallocated `strstream.freeze(false)` is called at the end of the tests.

Summary:
The size of the vector is being increased by `__n` during the call to `__move_range` and not by 1.
This fixes a test failure in `containers/sequences/vector/vector.modifiers/insert_iter_size_value.pass.cpp` when using ASAN.

If this workaround gets the bots green, then we have to find out
why the -dwarf-accel-tables=Enable option doesn't work as
expected on non-darwin platforms.

Prior to this commit fmul and fadd binary operators were being canonicalized for
both scalar and vector versions. We now canonicalize add, mul, and, or, and xor
vector instructions.

This reverts commit r221842 which was a revert of r221836 and of the
test parts of r221837.
This new version fixes an UB bug pointed out by David (along with
addressing some other review comments), makes some dumping more
resilient to broken input data and forces the accelerator tables
to be dumped in the tests where we use them (this decision is
platform specific otherwise).

Summary:
AsanOnSIGSEGV has some heuristics for detecting stack overflow, but
they don't cope with a PowerPC store-with-update instruction which
modifies sp and stores to the modified address in one instruction.
This patch adds some PowerPC-specific code to check for this case.
This fixes the last few cases of the stack-overflow test.
