12203cc7c3 Handle PCRel relocations with absolute values. Fixes PR8656.

2f5f90ad3e Implement PR8644: forwarding a memcpy value to a byval, 
allowing the memcpy to be eliminated.

Unfortunately, the requirements on byval's without explicit 
alignment are really weak and impossible to predict in the 
mid-level optimizer, so this doesn't kick in much with current
frontends.  The fix is to change clang to set alignment on all
byval arguments.

a6fd81dd7f a byval argument without an align can have an arbitrary alignment 
requirement on the input pointer.

59d2dad59e On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics, 
so don't claim they are.  They are allocated using DAG.getNode, so attempts
to access MemSDNode fields results in reading off the end of the allocated
memory.  This fixes crashes with "llc -debug" due to debug code trying to
print MemSDNode fields for these barrier nodes (since the crashes are not
deterministic, use valgrind to see this).  Add some nasty checking to try
to catch this kind of thing in the future.
