As per the discussion on D58375, we disable test that have optimizations under
the new PM. This patch adds -fno-experimental-new-pass-manager to RUNS that:
- Already run with optimizations (-O1 or higher) that were missed in D58375.
- Explicitly test new PM behavior along side some new PM RUNS, but are missing
this flag if new PM is enabled by default.
- Specify -O without the number. Based on getOptimizationLevel(), it seems the
default is 2, and the IR appears to be the same when changed to -O2, so
update the test to explicitly say -O2 and provide -fno-experimental-new-pass-manager`.

pass manager
Currently InstrProf lowering is not enabled for Clang PGO instrumentation in
the new pass manager. The following command
"-fprofile-instr-generate -fexperimental-new-pass-manager ..." is broken.
This CL enables InstrProf lowering pass for Clang PGO instrumentation in the
new pass manager.

This patch changes cc1 option for PGO profile use from
-fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>.
-fprofile-instr-use=<path> is now a driver only option.
In addition to decouple the cc1 option from the driver level option, this patch
also enables IR level profile use. cc1 option handling now reads the profile
header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM}
-- this is a common enum for -fprofile-instrument={}, for the profile
instrumentation), and invoke the pipeline to enable the respective PGO use pass.

This patch expands cc1 option -fprofile-instrument= with a new value: -fprofile-instrument=llvm
which enables IR level PGO instrumentation.
