Rong Xu 65711ad4e3 [PGO] Resubmit "MST based PGO instrumentation infrastructure" (r254021) ... This new patch fixes a few bugs that exposed in last submit. It also improves the test cases. --Original Commit Message-- This patch implements a minimum spanning tree (MST) based instrumentation for PGO. The use of MST guarantees minimum number of CFG edges getting instrumented. An addition optimization is to instrument the less executed edges to further reduce the instrumentation overhead. The patch contains both the instrumentation and the use of the profile to set the branch weights.
