romcc: Rewrite the test system
Differences: - The test logic is now only implemented in one place (pending the deletion of the old parts), whereas it previously was implemented both as make rules and as a pair of shell scripts. - Tests don't need to be registered anymore. Just adding a new file with the correct name is enough to have it tested. - The code is hopefully more readable and maintainable. - The new test script supports colors (if the standard output is a terminal and --nocolor was not passed on the command line). Things to do in follow-up patches: - Remove the old test code - Test or remove fail_test*.c, hello_world*.c and raminit_test*.c - Fix regressions that have built up over the years, while making sure not to introduce new ones - Makefile integration - Jenkins integration There are tests in the makefile that specify -fno-always-inline, but this option doesn't exist anymore, so I didn't port them over.
