Robert Flack ab78164ad8 Only check for matching arch and UUID when looking for dsym in vincinity of executable.
ModuleSpecs::FindMatchingModuleSpec looks for matching filenames but when
looking for the dSYM we should only be looking for a matching architecture and
and UUID. Jason pointed out this mistake in http://reviews.llvm.org/D9174 when
this function was incorrectly converted to not be Mac specific.

Test Plan:
Running LLDB on test/lang/c/shared_lib_stripped_symbols/a.out in a debugger I've
verified LocateDSYMInVincinityOfExecutable correctly locates the matching dSYM.

Alexander Kornienko 19bbeaf410 [clang-tidy] Disable google-readability-casting for .c files and their headers.
Some people have reasons to compile their .c files as C++ in some configurations
(e.g. for testing purposes), so just looking at LangOptions is not enough. This
patch disables the check on all .c files (and also for the headers included from
.c files).

Elena Demikhovsky 4aed59fc89 AVX-512: Enabled SSE intrinsics on AVX-512.
Predicate UseAVX depricates pattern selection on AVX-512.
This predicate is necessary for DAG selection to select EVEX form.
But mapping SSE intrinsics to AVX-512 instructions is not ready yet.
So I replaced UseAVX with HasAVX for intrinsics patterns.

Renato Golin b6b9e05687 Make Triple::parseARMArch use ARMTargetParser
Simplifying Triple::parseARMArch, leaving all the parsing to ARMTargetParser.

This commit also adds AArch64 detection to ARMTargetParser canonicalization,
and a two RedHat arch names (v{6,7}hl, meaning hard-float / little-endian).

Adding enough unit tests to cover the basics. Clang checks fine.

John Brawn 94fd963315 [ARM] Restructure cpu handling in the driver to mostly use the triple
Using the target cpu to determine some behaviour is sprinkled in
several places in the driver, but in almost all the information that
is needed can be found in the triple. Restructure things so that the
triple is used, and the cpu is only used if the exact cpu name is
needed.

Also add a check that the -mcpu argument is valid, and correct the
-march argument checking so that it handles -march=native correctly. I
would have liked to move these checks into the computation of the
triple, but the triple is calculated several times in several places
and that would lead to multiple error messages for the same thing.

Simon Pilgrim e054199354 [X86][SSE] Improve support for 128-bit vector sign extension
This patch improves support for sign extension of the lower lanes of vectors of integers by making use of the SSE41 pmovsx* sign extension instructions where possible, and optimizing the sign extension by shifts on pre-SSE41 targets (avoiding the use of i64 arithmetic shifts which require scalarization).

It converts SIGN_EXTEND nodes to SIGN_EXTEND_VECTOR_INREG where necessary, that more closely matches the pmovsx* instruction than the default approach of using SIGN_EXTEND_INREG which splits the operation (into an ANY_EXTEND lowered to a shuffle followed by shifts) making instruction matching difficult during lowering. Necessary support for SIGN_EXTEND_VECTOR_INREG has been added to the DAGCombiner.

Pavel Labath 39036ac31d [NativeProcessLinux] Fix handling of SIGSTOP
Summary:
Previously, NPL tried to reinject SIGSTOP into the inferior in an attempt to get the process to
start in the group-stop state. This was:
a) wrong (reinjection should be controlled by "process handle" lldb setting)
b) racy (it should use Resume for transparent resuming instead of RequestResume)
c) broken (llgs crashed on inferior SIGSTOP)

With this change, SIGSTOP is handled just like any other signal delivered to the inferior: we
stop all threads and report signal reception to lldb. SIGSTOP reinjection does not behave the
same way as it would outside the debugger, but simulating this is a hard problem and is not
normally necessary.

Test Plan: I have added a test which verifies we get SIGSTOP reports and we do not crash.

Duncan P. N. Exon Smith 0b73d71abb AsmPrinter: Compute absolute label difference directly
Create a low-overhead path for `EmitLabelDifference()` that emits a
emits an absolute number when (1) the output is an object stream and (2)
the two symbols are in the same data fragment.

This drops memory usage on Mach-O from 975 MB down to 919 MB (5.8%).
The only call is when `!doesDwarfUseRelocationsAcrossSections()` --
i.e., on Mach-O -- since otherwise an absolute offset from the start of
the section needs a relocation.  (`EmitLabelDifference()` is cheaper on
ELF anyway, since it creates 1 fewer temp symbol, and it gets called far
less often.  It's not clear to me if this is even a bottleneck there.)

(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;
see r236629 for details.)

Duncan P. N. Exon Smith 5435aa464a MC: Simplify MCSymbolData initialization and remove MCSymbol pointer
Finally remove the `MCSymbolData::Symbol` pointer.  It was still being
used to track whether `MCSymbolData` had been initialized, but this is
better tracked by the bitfield in `MCSymbol`.

The only caller of `MCSymbolData::initialize()` was `MCAssembler`, which
(other than `Symbol`) passed in all-0 values.  Replace all that
indirection with a default constructor.

The main point is a cleanup (and there's more cleanup to do), but there
are also some small memory savings.  I measured ~989 MB down to ~975 MB,
cutting a little over 1% off the top of `llc`.

(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;
see r236629 for details.)
