Ulrich Weigand b038a5268f [SystemZ] Define __GCC_HAVE_SYNC_COMPARE_AND_SWAP macros
Define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_[1248] macros on SystemZ.

This fixes a miscompile of GCC C++11 standard library headers
due to use of those macros in an ABI-changing manner.

See e.g. /usr/include/c++/4.8.5/ext/concurrence.h:

  // Compile time constant that indicates prefered locking policy in
  // the current configuration.
  static const _Lock_policy __default_lock_policy =
#ifdef __GTHREADS
#if (defined(__GCC_HAVE_SYNC_COMPARE_AND_SWAP_2) \
     && defined(__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4))
  _S_atomic;
#else
  _S_mutex;
#endif
#else
  _S_single;
#endif

A different choice of __default_lock_policy causes different
sizes of several of the C++11 data structures, which are then
incompatible when inlined in clang-compiled code with what the
(GCC-compiled) external library expects.

This in turn leads to various crashes when using std::thread
in code compiled with clang, as see e.g. via the ThreadPool
unit tests.  See PR 26473 for an example.

Richard Smith d79514e24b [modules] Separately track whether an identifier's preprocessor information and
name lookup information have changed since deserialization. For a C++ modules
build, we do not need to re-emit the identifier into the serialized identifier
table if only the name lookup information has changed (and in all cases, we
don't need to re-emit the macro information if only the name lookup information
has changed).

Reid Kleckner f27e752fe8 Fix attribute((mode([word|unwind_word]))) for x32
Patch by H.J. Lu

```
typedef unsigned int gcc_word __attribute__((mode(word)));
```
and

```
typedef unsigned int gcc_unwind_word __attribute__((mode(unwind_word)));
```
define the largest unsigned integer types which can be stored in a
general purpose register, which may not be the pointer type.  For x32,
they aren't pointer nor unsigned long.  We should

1. Make getUnwindWordWidth and getRegisterWidth virtual,
2. Override them for x32, similar to hasInt128Type.
3. Use getRegisterWidth for __attribute__((mode(word)));

This fixes PR 24706.

James Y Knight a3518ad0b7 Revert "Change of UserLabelPrefix default value from "_" to """
This reverts commit r258504.

This commit breaks (at least) sparc-rtems -- the OS (RTEMS) used to
override UserLabelPrefix to "", despite the arch (SPARC) having set it
to "_". Now, the OS doesn't override anymore, but the arch sets it to
"_", resulting in the wrong value. I expect this probably breaks other
OSes that overrode to "" before, as well. (Clearly we have some missing
test cases, here...)
