This patch upstreams support for Apple's implementation of anonymization.
The code is used internally to read and write BCSymbolMaps in the embedded
bitcode workflow. We need this logic upstream in order to upstream the part of 
dsymutil that deals with dSYMs generated for bitcode-enabled App Store builds.

If there's interest from the community I'd be more than happy to upstream the 
anonymization pass as well.

This is a slightly modified version of the code originally written by Steven Wu.
