Type trait parsing is all over the place at the moment with unary, binary and
n-ary C++11 type traits that were developed independently at different points
in clang's history.

There's no good reason to handle them separately -- there are three parsers,
three AST nodes and lots of duplicated handling code with slightly different
implementations and diags for each kind.

This commit unifies parsing of type traits and sets the stage for further
consolidation.

No change in behaviour other than more consistent error recovery.

GlobalOpt's CleanupConstantGlobalUsers function uses a worklist array to manage
constant users to be visited. The pointers in this array need to be weak
handles because when we delete a constant array, we may also be holding a
pointer to one of its elements (or an element of one of its elements if we're
dealing with an array of arrays) in the worklist.

Fixes PR17347.

The barrier pass is a temporary hack, and should go away soon. Nevertheless, if
we don't initialize it, then opt will not understand -barrier, and this will
break bugpoint (because when it dumps the passes from the default pass manager
-barrier will be there).

of MinGW older than 4.7 with incompatible C++ libraries.

This patch makes clang look for all MinGW versions from 4.7:

  4.7.0, 4.7.1, 4.7.2, 4.7.3
  4.8.0, 4.8.1, 4.8.2.

test_convenience_registers_16bit_with_process_attach fails due to
pr18200.  The test has a @expectedFailureFreeBSD decorator, but it
appears this does not catch a RuntimError exception raised in the test
infrastructure, so the test still reports failure.  For now just skip
it.

GCC 4.7 changed the MingW ABI. On the clang side this means that methods now
have the thiscall calling convention by default.

- Copy patterns with float/double types are enough.
- Fix typos in test case names that were using v1fx.
- There is no ACLE intrinsic that uses v1f32 type.  And there is no conflict of
  neon and non-neon ovelapped operations with this type, so there is no need to
  support operations with this type.
- Remove v1f32 from FPR32 register and disallow v1f32 as a legal type for
  operations.

getARMCPU and getLLVMArchSuffixForARM existed as very similar functions
in both ToolChain.cpp and Tools.cpp. Create a single implementation of
each in Tools.cpp, eliminate the duplicate and share via Tools.h.

Creates an 'arm' namespace in Tools.h to be used by any ARM-targetting tools.

This refactors some of the Darwin toolchain classification to give a more solid
distinction between the three primary Darwin platforms (OS X, IOS and IOS
simulator) so that a 4th choice can be added temporarily: embedded MachO
targets.

Longer term, this support will be factored out into a separate class and no
longer classified as "darwin-eabi", but the refactoring should still be useful.

a vector packed single/double fp operation followed by a vector insert.

The effect is that the backend coverts the packed fp instruction
followed by a vectro insert into a SSE or AVX scalar fp instruction.

For example, given the following code:
   __m128 foo(__m128 A, __m128 B) {
     __m128 C = A + B;
     return (__m128) {c[0], a[1], a[2], a[3]};
   }

 previously we generated:
   addps %xmm0, %xmm1
   movss %xmm1, %xmm0
 
 we now generate:
   addss %xmm1, %xmm0
