The function passes are disabled by default for optnone with the new
pass manager.  The pass is now enabled in clang backend if the
-finstrument-functions, -finstrument-function-entry-bare, or
-finstrument-functions-after-inlining instead of just for
optimization level different than -O0.

It fixes PR49143 and allows re-enable the eeprof-1.c test from
test-suite (disabled by D96521 <https://reviews.llvm.org/D96521>).
