Subject: Don't set full_profile in auto-profile [PR113765]

Don't set full_profile in auto-profile [PR113765]

auto-profile currently doesn't guarantee that it will set probabilities
on all edges because of zero basic block counts. Normally those edges
just have probabilities set by the preceding profile_estimate pass but
under -O0 profile_estimate pass doesn't run. The patch removes setting
of full_profile to true in auto-profile.

Tested on x86_64-pc-linux-gnu.
