[Utils] Allow update_test_checks to check function information

Browse Source 
Summary:
This adds a switch to the update_test_checks that triggers arguments and
other function annotations, e.g., personality, to be present in the
check line. If not set, the behavior should be the same as before.
If arguments are recorded, their names are scrubbed from the IR to allow
merging.

This patch includes D68153.
