[PGO] Move the instrumentation point closer to the value site. For terminator instructions, the value profiling instrumentation happens in a basic block other than where the value site resides. This CR moves the instrumentation point prior to the value site. Mostly NFC. llvm-svn: 264783

// Check the value profiling instrinsics emitted by instrumentation.
[PGO] cc1 option name change for profile instrumentation This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level. Review: http://reviews.llvm.org/D16730 llvm-svn: 259811

[PGO] test case cleanups 1. Make test case more focused and robust by focusing on what to be tested (linkage, icall) -- make it easier to validate 2. Testing linkages of data and counter variables instead of names. Counters and data are more relavant to be tested. llvm-svn: 259067
