Add --all-fixups to bisect.pl, to apply all patches and fixups.

bisect-runner.pl will minimally patch various files on a platform and
version dependent basis to get the build to complete. Normally it defers
doing this as long as possible - .SH files aren't patched until after
Configure is run, and C and XS code isn't patched until after miniperl is
built. If --all-fixups is specified, all the fixups are done before running
Configure.
