When we generate spill code, then decide we don't need
...
to spill after all, we weren't handling 2-instruction
spill sequences correctly (PPC Altivec). We need to
remove the store in this case. Removing the other
instruction(s) would be goodness but is not needed for
correctness, and isn't done here. 7331562.

Localize the optimization to ResolveLocationInAST(). The last valid AST location is now stored with ASTUnit. There still isn't optimal, however it's an improvement (with a much cleaner API). Having the client manage an "hint" is error prone and complex.
I wanted to land the major changes before finishing up the optimizations.
