This patch does the following:

* Remove <__config> includes from some container tests.
* Guards uses of std::launch::any in async tests because it's an extension.
* Move "test/std/extensions" to "test/libcxx/extensions"
* Moves various non-standard tests including those in "sequences/vector",
  "std/localization" and "utilities/meta".

Matthias Braun f3619b8212 RegisterPressure: Fix default lanemask for missing regunit intervals
In case of missing live intervals for a physical registers
getLanesWithProperty() would report 0 which was not a safe default in
all situations. Add a parameter to pass in a safe default.
No testcase because in-tree targets do not skip computing register unit
live intervals.

Also cleanup the getXXX() functions to not perform the
RequireLiveIntervals checks anymore so we do not even need to return
safe defaults.

Akira Hatanaka 10aced824a [Parser] Clear the TemplateParamScope bit of the current scope's flag
if we are parsing a template specialization.

This commit makes changes to clear the TemplateParamScope bit and set
the TemplateParamParent field of the current scope to null if a template
specialization is being parsed.

Before this commit, Sema::ActOnStartOfLambdaDefinition would check
whether the parent template scope had any decls to determine whether
or not a template specialization was being parsed. This wasn't correct
since it couldn't distinguish between a real template specialization and
a template defintion with an unnamed template parameter (only template
parameters with names are added to the scope's decl list). To fix the
bug, this commit changes the code to check the pointer to the parent
template scope rather than the decl list.

Eric Fiselier bc32b5cf8f Move INVOKE tests into test/libcxx sub-tree.
Testing the concrete implementation of INVOKE means calling the implementation
specific names `__invoke` and `__invoke_constexpr`. For this reason the test
are non-standard. For this reason it's best if the tests live outside of the
`test/std` directory.

Carlo Bertolli 6eee9061ac [OPENMP] Enable correct generation of runtime call when target directive is separated from teams directive by multiple curly brackets
http://reviews.llvm.org/D18474

This patch fixes a bug in code generation of the correct OpenMP runtime library call in presence of target and teams, when target is separated by teams with multiple curly brackets. The current implementation will not be able to see the teams directive inside target and issue a call to tgt_target instead of the correct one tgt_target_teams.

Hal Finkel 1b66f7e3c8 [LoopVectorize] Keep hints from original loop on the vector loop
We need to keep loop hints from the original loop on the new vector loop.
Failure to do this meant that, for example:

  void foo(int *b) {
  #pragma clang loop unroll(disable)
    for (int i = 0; i < 16; ++i)
      b[i] = 1;
  }

this loop would be unrolled. Why? Because we'd vectorize it, thus dropping the
hints that unrolling should be disabled, and then we'd unroll it.

Reid Kleckner f463a8a424 Avoid -Wshadow warnings about constructor parameters named after fields
Usually these parameters are used solely to initialize the field in the
initializer list, and there is no real shadowing confusion.

There is a new warning under -Wshadow called
-Wshadow-field-in-constructor-modified. It attempts to find
modifications of such constructor parameters that probably intended to
modify the field.

It has some false negatives, though, so there is another warning group,
-Wshadow-field-in-constructor, which always warns on this special case.
For users who just want the old behavior and don't care about these fine
grained groups, we have a new warning group called -Wshadow-all that
activates everything.

Fixes PR16088.

Adam Nemet 0ba164bbcb [LoopDist] Emit optimization remarks (-Rpass*)
I closely followed the precedents set by the vectorizer:

* With -Rpass-missed, the loop is reported with further details pointing
to -Rpass--analysis.

* -Rpass-analysis reports the details why distribution has failed.

* Regardless of -Rpass*, when distribution fails for a loop where
distribution was forced with the pragma, a warning is produced according
to -Wpass-failed.  In this case the analysis info is also printed even
without -Rpass-analysis.

Hal Finkel 50316d95a9 [Inliner] Preserve llvm.mem.parallel_loop_access metadata
When inlining a call site with llvm.mem.parallel_loop_access metadata, this
metadata needs to be propagated to all cloned memory-accessing instructions.
Otherwise, inlining parts of the loop body will invalidate the annotation.

With this functionality, we now vectorize the following as expected:

  void Body(int *res, int *c, int *d, int *p, int i) {
    res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
  }

  void Test(int *res, int *c, int *d, int *p, int n) {
    int i;

  #pragma clang loop vectorize(assume_safety)
    for (i = 0; i < 1600; i++) {
      Body(res, c, d, p, i);
    }

Marcin Koscielnicki 7b32957852 [PowerPC] Fix the EH_SjLj_Setup pseudo.
This instruction is just a control flow marker - it should not
actually exist in the object file.  Unfortunately, nothing catches
it before it gets to AsmPrinter.  If integrated assembler is used,
it's considered to be a normal 4-byte instruction, and emitted as
an all-0 word, crashing the program.  With external assembler,
a comment is emitted.

Fixed by setting Size to 0 and handling it in MCCodeEmitter - this
means the comment will still be emitted if integrated assembler
is not used.

This broke an ASan test, which has been disabled for a long time
as a result (see the discussion on D19657).  We can reenable it
once this lands.
