When mangling function template specialization, mangle the type encoding of the original function template. Also, port mangle.cpp and function-template-specialization.cpp over to using FileCheck.

PCH: When writing PCH files, tweak the predicate function deciding whether to mark a decl as "external" to be closer to reality. 

This still isn't perfect, but I believe it is conservatively accurate at marking decls which IRgen needs to see, while still keeping the "deserialization footprint" on Cocoa.h.

PCH: When deserializing an explicit "external definition", don't pass it to HandleTopLevelDecl -- this is already being done inside the reader.

This is something of a hack, since whether the reader actually did this depends on the "isConsumerInterestedIn" predicate. I think we need to rework how this works, but I need to discuss with Doug.

Fix PR4910: Broken logic in coalescer means when a physical register liveness is being shortened, the sub-registers were not. The symptom is the register allocator could not find a free register for this particular test.

 - Doesn't actually work yet because only module level asm's get correctly marked as externally visible in the PCH.

 - Other things like 'clang-cc foo.ast -ast-dump' now work, as well.

constants out of loops. These aren't covered by the regular LICM
pass, because in LLVM IR constants don't require separate
instructions. They're not always covered by the MachineLICM pass
either, because it doesn't know how to unfold folded constant-pool
loads. This is somewhat experimental at this point, and off by
default.
