[PGO] Change profile use cc1 option to handle IR level profiles 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.

Don't crash when passing a non-existent file to -fprofile-instr-use=. Fixes a regression from r229434. llvm-svn: 234141 2015-04-06 12:16:48 +08:00
Display profile file name when emitting a file not found diagnostic. When a profile file cannot be opened, we used to display just the error message but not the name of the profile the compiler was trying to open. This will become useful in the next set of patches that introduce GCC-compatible flags to specify profiles. llvm-svn: 240715 2015-06-26 06:56:00 +08:00			`// CHECK: error: Could not read profile {{.*}}.nonexistent.profdata:`
