Add flags to disable profile generation.

[Diego Novillo]

This patch adds flags -fno-profile-instr-generate and
-fno-profile-instr-use, and the GCC aliases -fno-profile-generate and
-fno-profile-use.

These flags are used in situations where users need to disable profile
generation or use for specific files in a build, without affecting other
files.

OK to commit?


Thanks.  Diego.
