This reverts commit 93c7e6161e1adbd2c7ac81fa081823183035cb64.
This commit got approved first, but was dependant on another one going in (The one pretty printing attribute values). I'll reapply when the other one is in.

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 fixes an issue where MS inline assembly containing xgetbv wouldn't
be marked as clobbering EAX:EDX. Test for that forthcoming on the Clang
side.

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.

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.
As before, the instruction already performs the correct operation and we're
just using a different type for convenience, so we want a true nop-cast.

llvm-svn: 217159
Summary:
This adds a support for the .clang-tidy file reading using
FileOptionsProvider, -dump-config option, and changes tests to not depend on
default checks set.

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:

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%.

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.

Summary: There are still some functions which should be renamed, but they are inherited from the generic MC classes.

r216662 changed the default ABI for 32-bit ARM targets to be "aapcs"
when no environment is given in the triple, however NetBSD requires it
to be "apcs-gnu".

Chained origins make plain memory stores async-signal-unsafe.
We already disable it inside signal handlers.
This change grabs all origin-related locks before fork() and releases
them after fork() to avoid a deadlock in the child process.

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.

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.
