Experimental support for a meaningful __is_swappable<T>::value.  This does not appear to be strictly needed for correct functioning of the library.  If it causes any problems, I'd rather pull it sooner rather than later.

This commit caused regressions in i386 flops-[568], matrix, salsa20,

Turning on cxx_nullptr exposed a latent bug in is_function, causing nullptr to wrongly classify as a function.  Fixed.

Fixes valgrind errors in the CellSPU backend.

floating-point comparison, generate a mask of 0s or 1s, and generally
DTRT with NaNs.  Only profitable when the user wants a materialized 0
or 1 at runtime.  rdar://problem/5993888

Don't use stdint.h; including it directly is not allowed from LLVM code because it doesn't exist on MSVC.

constant-expression, and, therefore, an unevaluated operand. Make it
so.

Add TargetRegisterInfo::hasSubClassEq and use it to check for compatible
register classes instead of trying to list all register classes in
X86's getLoadStoreRegOpcode.

This patch is another step in the direction of adding vector select. In this
patch we add a flag to enable a new type legalization decision - to promote
integer elements in vectors. Currently, the rest of the codegen does not support
this kind of legalization.  This flag will be removed when the transition is
complete.

The parser is not fit to deal with stale PCHs, too many invariants do not hold up. rdar://9530587.

Fix broken test on windows. To get operator new working, we need size_t, for which we need to figure out a way to resolve standard include paths in the test.
