The interop tests weren't updated when regex support was added to
runtest for matching output data. This was causing a bunch of
implementations to silently fail while testing interop. Fix runtest.py
to fail on bad test data and fix 21 implementations with the old style
output matches.
- Remove most of the step5 excludes in the Makefile except for ones
which don't have TCO capability at all (or the implementation is too
slow): bash, make, mal, matlab.
- Make perf_EXCLUDES consistent with other excludes.
- Add a print-FOO target which prints the resolved value of Makefile
variable FOO. For example, `make print-IMPLS` to print the list of
implementations.
