Keep track of the file ID corresponding to the original file used to
build a precompiled header. Use this information to eliminate the call
to SourceManager::getLocation() while loading a precompiled preamble,
since SourceManager::getLocation() itself causes unwanted
deserialization.
Fixed <rdar://problem/9399352>.
