  [Driver] Remove ignored Flag form of -fauto-profile/-fprofile-sample-use

The Flag form options are accepted and silently ignored, which can be
surprising. The Eq form is supposed to be used instead, e.g.
-fprofile-sample-use=a.afdo.

Since we does not intend to support GCC's "fbaata.afdo" filename, just
remove the two options. While here, clean up code as -fauto-profile= is
an alias.
