Comments: GVN: merge overflow intrinsics with non-overflow instructions.

When an overflow intrinsic is followed by a non-overflow instruction,
replace the latter with an extract. For example:

  %sadd = tail call { i32, i1 } @llvm.sadd.with.overflow.i32(i32 %a, i32 %b)
  %sadd3 = add i32 %a, %b

Here the add statement will be replaced by an extract.

When an overflow intrinsic follows a non-overflow instruction, a clone
of the intrinsic is inserted before the normal instruction, which makes
it the same as the previous case. Subsequent runs of GVN can then clean
up the duplicate instructions and insert the extract.

This fixes PR8817.

Comments: Removed code that conditionally included pthread.h for mingw.
This header is generally not available on mingw and can cause build errors.
The windows host code does provide timespec definition that can be used for
mingw case.

Comments: IR: add a second ordering operand to cmpxhg for failure

The syntax for "cmpxchg" should now look something like:

	cmpxchg i32* %addr, i32 42, i32 3 acquire monotonic

where the second ordering argument gives the required semantics in the case
that no exchange takes place. It should be no stronger than the first ordering
constraint and cannot be either "release" or "acq_rel" (since no store will
have taken place).

Comments: Sema: produce error when invalid ordering is passed to atomic builtin

This is a conservative check, because it's valid for the expression to be
non-constant, and in cases like that we just don't know whether it's valid.
