instructions. It attempts to create high-level multi-operand GEPs,
though in cases where this isn't possible it falls back to casting
the pointer to i8* and emitting a GEP with that. Using GEP instructions
instead of ptrtoint+arithmetic+inttoptr helps pointer analyses that
don't use ScalarEvolution, such as BasicAliasAnalysis.

Also, make the AddrModeMatcher more aggressive in handling GEPs.
Previously it assumed that operand 0 of a GEP would require a register
in almost all cases. It now does extra checking and can do more
matching if operand 0 of the GEP is foldable. This fixes a problem
that was exposed by SCEVExpander using GEPs.

Fix up the Windows portion of Atomic.h.  This is untested, but it is my best understanding of what should work.
I'd be much obliged if someone on MSVC++ could try this out and let me know if it works.

This patch allows clang to generate code for declared properties on the GNU runtime.  As with @synchronized, this requires some extra functions that are included with other libraries (not with the GNU runtime itself) and so will cause linker errors when these are not present.
