Add support for the profile-func-internal-id parameter to the coverage callback.
Without this change, the function identifier passed to __coverage_callback
(enabled with param=coverage-callback=1) does not match the values emitted in
the .gcno file. Because the function profile_id is typically more unique
(typically 32 bits) than the function internal id (typically 16 bits), it can be
desirable to have the profile_id used to identify a function as opposed to the
function internal id.

profile-func-internal-id parameter to the coverage callback
