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

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.

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.

Do the right thing for zero-initializing VLAs that don't have a zero

Support the zero-initialization of VLAs when that really means a zero

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).

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.
