* Fix self-swap. Patch from Casey Carter.

* Remove workarounds and tests for types with deleted move constructors. This
  was originally added as part of a LWG proposed resolution that has since
  changed.

* Re-apply most recent PR for LWG 2769.

* Re-apply most recent PR for LWG 2754. Specifically fix the SFINAE checks to
  use the decayed type.

* Fix tests to allow moved-from std::any's to have a non-empty state. This is
  the behavior of MSVC's std::any.

* Various whitespace and test fixes.

'warn_attribute_wrong_decl_type' has to stay in sync with
'enum AttributeDeclKind' which is much easier when they line up.

Revert the -print-libgcc-file-name change as the new test fails
on Darwin. It needs to be updated to run the libgcc part only on systems
supporting that rtlib.

Also use uint64_t instead of uintX_t so that you don't have to
think about two different cases to verify that the code is correct.

As the code is now, calling omp_get_schedule() when OMP_SCHEDULE=static_steal
will cause an assert.

If we're going to canonicalize IR towards select of constants, try harder to create those.
Also, don't lose the metadata.

This is actually 4 related transforms in one patch:
      // select X, (sext X), C --> select X, -1, C
      // select X, (zext X), C --> select X,  1, C
      // select X, C, (sext X) --> select X, C, 0
      // select X, C, (zext X) --> select X, C, 0

Remove the brace default initializer to see if this is what's causing
the msvc crash.

llvm-svn: 283574

This is the primary suspect for causing the msvc crash, now that vector of
smart pointers was proven to be safe. Probably the default {}-initializer
is the problem.

Make the -print-libgcc-file-name option print an appropriate compiler
runtime library, that is libgcc.a if gcc runtime is used
and an appropriate compiler-rt library if that runtime is used.

The main use for this is to allow linking executables built with
-nodefaultlibs (e.g. to avoid linking to the standard C++ library) to
the compiler runtime library, e.g. using:

  clang++ ... -nodefaultlibs $(clang++ ... -print-libgcc-file-name)

in which case currently a program built like this linked to the gcc
runtime unconditionally. The patch fixes it to use compiler-rt libraries
instead when compiler-rt is the active runtime.

This is a new tool built on top of the new YAML ouput generated from
optimization remarks.  It produces HTML for easy navigation and
visualization.

The tool assumes that hotness information for the remarks is available
(the YAML file was produced with PGO).  It uses hotness to list the
remarks prioritized by the hotness on the index page.  Clicking the
source location of the remark in the list takes you the source where the
remarks are rendedered inline in the source.

For now, the tool is meant as prototype.

It's written in Python.  It uses PyYAML to parse the input.

Previously, we marked the branch conditions of latch blocks uniform after
vectorization if they were instructions contained in the loop. However, if a
condition instruction has users other than the branch, it may not remain
uniform. This patch ensures the conditions we mark uniform are only used by the
branch. This should fix PR30627.
