Guard function->cond_uids access [PR114601]

PR114601 shows that it is possible to reach the condition_uid lookup
without having also created the fn->cond_uids, through
compiler-generated conditionals. Consider all lookups on non-existing
maps misses, which they are from the perspective of the source code, to
avoid the NULL access.

PR gcov-profile/114601

gcc/ChangeLog:

* tree-profile.cc (condition_uid): Guard fn->cond_uids access.

gcc/testsuite/ChangeLog:

* gcc.misc-tests/gcov-pr114601.c: New test.

This is still failing as of r14-9822 (after the second PR114599#c7 fix).
