- Moves most parts to //testing/lit_test to be consistent with //testing/file_test. - Separates the autoupdate script out because it's shared between lit_test and file_test now, not lit-specific. - Renames scripts to autoupdate_testdata (or autoupdate_lit_testdata for explorer's extra) to be more consistent with the non-lit-specific setup. - Switches from execv to subprocess.call to head off a subtle issue regarding execution of multiple scripts, which we're likely to want in the future. Mostly in this PR because everything was already being touched. - Removes autoupdate's dependency on merge_output in order to (a) better support the division of lit and non-lit logic and (b) remove a subprocess, for reasons similar to file_test's removal of subprocesses.
