ceab39f0b7 Fix multiple-return-value-to-first-class-aggregates autoupgrade to
correctly handle the case where multiple-return-value constructs
were used to return one or zero values.

e089160d10 InsertValue and ExtractValue constant expressions are always
folded. Remove code that handled the case where they aren't
folded, and remove bitcode reader/writer support for them.

6d116bc7ce Revert (52748 and friends):
Move GetConstantStringInfo to lib/Analysis. Remove
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

This unbreaks llvm-gcc bootstrap.
