Peter Collingbourne 7ce13fc940 OpenCL: add support for __kernel, kernel keywords and EXTENSION, 
FP_CONTRACT pragmas.  Patch originally by ARM.

John McCall 8322c3a197 Give some convenient idiomatic accessors to Stmt::child_range and 
Stmt::const_child_range, then make a bunch of places use them instead
of the individual iterator accessors.

John McCall ad7c5c1657 Reorganize CodeGen{Function,Module} to eliminate the unfortunate 
Block{Function,Module} base class.  Minor other refactorings.

Fixed a few address-space bugs while I was there.

John McCall 2725aa13ea Do the right thing for zero-initializing VLAs that don't have a zero 
bit-pattern.  It's not clear that this is actually useful given current
language restrictions.

John McCall ed1ae86ac6 Move all the cleanups framework code into a single file.

John McCall ce1de6172c Better framework for conditional cleanups; untested as yet. 
I'm separately committing this because it incidentally changes some
block orderings and minor IR issues, like using a phi instead of
an unnecessary alloca.

John McCall a08ffd22d5 Support the zero-initialization of VLAs when that really means a zero 
bit-pattern.  Continue punting on zero-initializing VLAs with a nonzero
pattern.

John McCall 5461a7523f When simplifying a cleanup's entry by merging it into a single predecessor, 
replace all uses of the entry with the predecessor.  There are no cleanups
relying on this right now, but if we ever want a cleanup with a phi inside
it, this will be important.

John McCall aa6d98c160 Factor out most of the extra state in a FunctionProtoType into a separate 
class to be passed around.  The line between argument and return types and
everything else is kindof vague, but I think it's justifiable.

John McCall e5dd32da11 Teach PopCleanupBlock to correctly handle the possibility of branching through 
a EH-only cleanup as part of a fallthrough branch-through.  That this happens
for this test case is actually a separate bug.

John McCall 0077b22aa4 If we're resolving all outstanding fixups, and there are multiple fixups 
for the same destination, then we must potentially rewrite the initial branch
of every fixup.  Without this patch, a short-circuit check meant to prevent
a switch case from being redundantly added was preventing later fixups from
being processed.  Fixes PR8175 (again).

John McCall f09d96f76d Adjust a fixup's starting branch if it's being resolved because 
it reached the outermost scope and it hasn't yet been forwarded
to a cleanup.  Fixed PR8175.

John McCall 7f9c92a9a0 When emitting a new-expression inside a conditional expression, 
the cleanup might not be dominated by the allocation code.
In this case, we have to store aside all the delete arguments
in case we need them later.  There's room for optimization here
in cases where we end up not actually needing the cleanup in
different branches (or being able to pop it after the
initialization code).

Also make sure we only call this operator delete along the path
where we actually allocated something.

Fixes rdar://problem/8439196.

John McCall 824c2f537c Implement the EH cleanup to call 'operator delete' if a new-expression throws 
(but not if destructors associated with the full-expression throw).
