(Re-apply patch after bug fixing) This diff makes sure that the driver does not pass -fomit-frame-pointer or -momit-leaf-frame-pointer to the frontend when -pg is used. Currently, clang gives an error if -fomit-frame-pointer is used in combination with -pg, but -momit-leaf-frame-pointer was forgotten. Also, disable frame pointer elimination in the frontend when -pg is set. Patch by Stefan Kempf. llvm-svn: 253886
