Fix profile scaling in tree-inline.cc:initialize_cfun

[Jan Hubicka]

Hi,
initialize_cfun calls
 profile_count::adjust_for_ipa_scaling (&num, &den);
but then the result is never used.  This patch fixes it.  Overall scalling
of entry/exit block is bit sloppy in tree-inline.  I see if I can clean it up.

Bootstrapped/regtested x86_64-linux, comitted.

        * tree-inline.cc (initialize_cfun): Use num and den for scaling.
