profile: Another musttail fix [PR119618]
As the following testcase shows, sometimes we can have debug stmts
after a musttail call and profile.cc in that case would incorrectly
allow the edge from that, causing musttail error and -fcompare-debug
failure (because if there are no debug stmts after it, then musttail
is found there and the edge is ignored).
The following patch uses gsi_last_nondebug_bb instead of gsi_last_bb
to find the musttail call. And so that we don't uselessly skip over
debug stmts at the end of many bbs, the patch limits it to
cfun->has_musttail functions.

* profile.cc (branch_prob): Only check for musttail calls if
cfun->has_musttail. Use gsi_last_nondebug_bb instead of gsi_last_bb.
* c-c++-common/pr119618.c: New test.
