[PGO] Rename the profdata filename to avoid the conflict b/w tests. Two tests diag_mismatch.ll and diag_no_funcprofdata.ll generates the same profdata filename which can conflict in current test runs. This patch renames them to have different names. llvm-svn: 255158

[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. Differential Revision: http://reviews.llvm.org/D12781 llvm-svn: 255132
