[X86] Don't fail disassembly if REX.R/REX.B is used on an MMX register. Similar fix to not fail to disassembler CR9-CR15 references.

[ASan/Win] Add basic support for MemoryRangeIsAvailable and DumpProcessMap to make it easier to debug startup shadow mapping failures

This increases the limit from 4M locations to 16M, reserving
64Mb virtual memory. Chrome has >5M unique coverage locations with coverage=3.

This is a re-commit of r224838 + r224839, previously reverted in r224850.
Test failures were likely (still can not reproduce) caused by two lit tests
using the same name for an intermediate build target.

llvm-svn: 224853

This will prevent ASan bots from hanging / timing out

Inferring nuw caused some clang tests to change their output.

Flaky failures on the build bots.

A multiply cannot unsigned wrap if there are bitwidth, or more, leading
zero bits between the two operands.

Constant contains the isAllOnesValue and isNullValue predicates, not
ConstantInt.

We already utilize this logic for reducing overflow intrinsics, it makes
sense to reuse it for normal multiplies as well.

Teach disassembler to handle illegal immediates on (v)cmpps/pd/ss/sd instructions. Instead of rejecting we'll just generate the _alt forms that don't try to alter the mnemonic. While I'm here, merge some common code in the Instruction printers for the condition code replacement and fix the mask on SSE to be 3-bits instead of 4.

getPrintable has an overload which takes a bool.  This means that const
qualified Exprs would get forwarded to the bool overload instead of the
Expr overload.

When materializing constant i1 values, they must be zero extended. We represent
i1 values as [0, 1], not [0, -1], in i32 registers. As it turns out, this code
path was dead for i1 values prior to r216006 (which is why this did not manifest in
miscompiles until recently).

Fixes -O0 self-hosting on PPC64/Linux.

The current code leaves the first event in the trace part uninitialized
(from the previous thread). It can cause unpredictable behavior
during stack/mutexset restoration.
Initialize the first event to a fake harmless memory access.

If a regular symbol has microMIPS-bit we need to stop linking. Now the
LLD does not check the `applyRelocation` return value and continues
linking anyway. As a temporary workaround use the `llvm_unreachable`
call to stop the linker.

llvm-svn: 224831

The LLD output in the YAML mode depends on LLD_RUN_ROUNDTRIP_TEST
environment variable. Do not check unimportant YAML items like section-name.

The change is rather large but mainly it just adds handling of new relocations,
PLT entries etc.

Bob Wilson pointed out the unnecessary checks that had been committed to the
instruction check predicates.  The check was meant to ensure that the check was
not accidentally applied to non-ARM instructions.  This is better served as an
assertion rather than a condition check.

This is mostly useful for testing, as the only other way of specifying
activation options (Android system property) is system-wide and affects
concurrently running tests.
