Mark test as passing on all x86, which it should,
although I don't think anyone cares about this
feature except Darwin. PR 4825.

r83391 was completely broken since Twines keep references to their inputs, and
some of the inputs were temporaries. Here's a real fix for the miscompilation.
Thanks to sabre for pointing out the problem.

Don't constant propagate byval pointers, since they are not really pointers, but
rather structs passed by value.
This fixes PR5038.

Merge 82177 from mainline.
Use __attribute__((__used__)) if GCC >= 3.1 (seems to be the oldest GCC
supporting this attribute).

Rework getPersonalityIndex slightly - 0 is now a valid and not-NULL
personality function.

Change the marker byte for stubs from 0xcd to 0xce (another form of
interrupt instruction, which shouldn't arise any other way). 0xcd is
also used by JITMemoryManager to initialize the buffer to garbage,
which means it could appear following a noreturn call even when
that is not a stub, confusing X86CompilationCallback2. PR 4929.

Don't pull a load through a callseq_start if the load's chain
has multiple uses, as one of the other uses may be on a path
to a different node above the callseq_start, because that
leads to a cyclic graph. This problem is exposed when
-combiner-global-alias-analysis is used. This fixes PR4880.

If we've pushed registers onto the stack, but aren't adjusting the stack pointer
(i.e., there are no local variables and stuff), we still need to output FDE
information for the pushed registers.

If we're emitting additional CIEs due to personality functions
don't emit the default one. Explicitly check for the NULL

Make TypeBuilder's result depend on the LLVMContext it's passed.
TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.

Fixed a test that ensures the LocalRewriter does not attempt to
avoid reloads by reusing clobbered registers.
