[PATCH] D27689: Module: hash the pcm content and use it as SIGNATURE for implicit modules.

I've rebased the patch on ToT and cleaned a few things up.

Sadly, the clang/test/Modules/diagnostic-options-out-of-date.m test fails because r293123 makes the command-line diagnostic options affect the AST, and thus makes -Wconversion vs -Wno-conversion change ASTFileSignature.

I'm not sure how to move forward.
