[PATCH] D11933: Extending debug ranges

[Vikram TV via llvm-commits]

First, sorry for submitting this after a long gap.

The following changes have been made:
a. Make OpenRanges usage local to every mbb.
b. Rewrite 'join' routine - generic implementation by looking at all predecessors of an mbb to extend the debug value ranges across mbb by using IncomingLocs as suggested in the review comment. Previously, the implementation was limited to 1 and 2 predecessors.
