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.
