Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass."" 
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Rong Xu 2611ff8a27 [PGO] Use %t as the temporary profdata filename in the test cases.

Rong Xu 7dd9b1ea75 [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.

Rong Xu f430ae40cf [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.
