Don't cause ICEs when auto profile file is not found with checking
Currently, on a checking enabled compiler when -fauto-profile does
not find the profile feedback file it errors out with assertation
failures. Add proper errors for this case.

* auto-profile.c (read_profile): Replace asserts with errors
when file does not exist.
* gcov-io.c (gcov_read_words): Dito.
