When the destination register of an add immediate instruction is
explicitly specified, encoding T1 is preferred, else encoding T2 is
preferred.

It appears that our use of the imp-use and imp-def flags with
sub-registers is not yet robust enough to support this.
The failing test case is complicated, I am working on a reduction.

system for macro-backed source locations. The old APIs are preserved for
legacy users.
This was intended to land with the main work of instantiation ->
expansion, but despite running it by Doug over a month ago, I forgot to
commit it. Very sorry for that...

of the function in question when applicable (that is, not for blocks).
Patch by Joerg Sonnenberger with some stylistic tweaks by me.
When discussing this weth Joerg, streaming the decl directly into the
diagnostic didn't work because we have a pointer-to-const, and the
overload doesn't accept such. In order to make my style tweaks to the
patch, I first changed the overload to accept a pointer-to-const, and
then changed the diagnostic printing layer to also use
a pointer-to-const, cleaning up a gross line of code along the way.

- Duplicate some store patterns to their AVX forms!
- Catched a bug while restricting the patterns subtarget, fix it
and update a testcase to check it properly

collision between C99 hexfloats and C++0x user-defined literals by
giving C99 hexfloats precedence. Also, warning about user-defined
literals that conflict with hexfloats and those that have names that
are reserved by the implementation. Fixes <rdar://problem/9940194>.

sure that all of the CXXConversionDecls go into the same
bucket. Otherwise, name lookup might not find them all. Fixes

This makes the code duplication of implicit special member handling even worse,
but the cleanup will have to come later. For now, this works.
Follow-up with tests for explicit defaulting and enabling the __has_feature
flag to come.

code is inserted to first check if the current stacklet has enough
space. If so, space is allocated by simply decrementing the stack
pointer. Otherwise a runtime routine (__morestack_allocate_stack_space
in libgcc) is called which allocates the required memory from the
heap.

Empty lookups can occur in the DeclContext map when we are chaining PCHs, where
the empty lookup indicates that we already looked in ExternalASTSource.

from DYNAMIC_STACKALLOC.
Two new pseudo instructions (SEG_ALLOCA_32 and SEG_ALLOCA_64) which
will match X86SegAlloca (based on word size) are also added. They
will be custom emitted to inject the actual stack handling code.

X86. Modify the pass added in the previous patch to call this new
code.
This new prologues generated will call a libgcc routine (__morestack)
to allocate more stack space from the heap when required
