Reid Kleckner 6b3a94065b Win64: Add the uwtable attribute by default on Win64
Now that LLVM emits correct .pdata and .xdata for inline functions, we
can reenable this.

Reid Kleckner 7c4059eb89 MC Win64: Put unwind info for COMDAT code into the same COMDAT group
Summary:
This fixes a long standing issue where we would emit many little .text
sections and only one .pdata and .xdata section. Now we generate one
.pdata / .xdata pair per .text section and associate them correctly.

Fixes PR19667.

This adds the printing of more load commands, so that the normal load commands

Justin Bogner cc0d7eeb6d profile: Avoid name collisions between instrumentation and runtime
The naming scheme we're using for counters in profile data shares a
prefix with some fixed names we use for the runtime, notably
__llvm_profile_data_begin and _end. Embarrassingly, this means a
function called begin() can't be instrumented.

This modifies the runtime names so as not to collide with the
instrumentation.

Daniel Sanders e5018b6c00 [mips] Mark aggregates returned in registers with the 'inreg' attribute.
Summary:
This allows us to easily find them in the backend after the aggregates have
been lowered to other types. This is important on big-endian targets using
the N32/N64 ABI's since these ABI's must shift small structures into the
upper bits of the register.

Follow up to r217138, extending the logic to other NEON-immediate instructions.

Jan Vesely c0ae1a038f build/cmake: Fix CMP0023 warning with libffi
Fixes:
CMake Warning (dev) at lib/ExecutionEngine/Interpreter/CMakeLists.txt:16 (target_link_libraries):
  Policy CMP0023 is not set: Plain and keyword target_link_libraries
  signatures cannot be mixed.  Run "cmake --help-policy CMP0023" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  The keyword signature for target_link_libraries has already been used with
  the target "LLVMInterpreter".  All uses of target_link_libraries with a
  target should be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * cmake/modules/AddLLVM.cmake:345 (target_link_libraries)

Samuel Benzaquen ab005ed0c0 Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
Summary:
Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
 - Make some code type agnostic and move it to the cpp file.
 - Return a DynTypedMatcher instead of storing the object in MatcherOps.

This change reduces the number of symbols generated in Registry.cpp by
~19%, the object byte size by ~17% and the compilation time (in non-release mode) by ~20%.

Daniel Sanders ed39f58390 [mips] Zero-sized structs cannot be ignored in MipsABIInfo::classifyReturnType() for O32
Summary:
They are returned indirectly which causes the other arguments to move to
the next argument slot.

With this, utils/ABITest does not discover any failing cases in the first
500 attempts on big/little endian for O32. Previously some of these failed.
Also tested N32/N64 little endian (big endian has other known issues) with
no issues.

Tim Northover bb72e6c804 AArch64: fix big-endian immediate materialisation
We were materialising big-endian constants using DAG nodes with types different
from what was requested, followed by a bitcast. This is fine on little-endian
machines where bitcasting is a nop, but we need a slightly different
representation for big-endian. This adds a new set of NVCAST (natural-vector
cast) operations which are always nops.

Chandler Carruth 2e5134f8f4 [x86] Teach the new v4i32 shuffle lowering some more tricks to recognize
vzext patterns and insert-element patterns that for SSE4 have dedicated
instructions.

With this we can enable the experimental mode in a regression test that
happens to cover some of the past set of issues. You can see that the
new logic does significantly better here on the floating point cases.

A follow-up to this change and the previous ones will hoist the logic
into helpers so it can be shared across element type sizes as in this
particular case it generalizes cleanly.
