void BitcodeReaderValueList::ResolveConstantForwardRefs ( )

ResolveConstantForwardRefs - Once all constants are read, this method bulk resolves any forward references.

ResolveConstantForwardRefs - Once all constants are read, this method bulk resolves any forward references. The idea behind this is that we sometimes get constants (such as large arrays) which reference *many* forward ref constants. Replacing each of these causes a lot of thrashing when building/reuniquing the constant. Instead of doing this, we look at all the uses and rewrite all the place holders at once for any constant that uses a placeholder.
