Changed the --variants option to --test-variants and added a new --compile-variants option for variants that are only compiled (not tested). The former still defaults to 'opt' and the latter defaults to 'debug,fast'. Also changed the behavior when no tests are specified from just compiling to running the 'quick' tests. As a result, a plain 'util/regress' invocation will now compile (but not test) the debug and fast builds, and compile and run the quick regressions on the opt build. This should be the default set of tests that are run before committing. Since the nightly regressions use this same script, this will also be the new nightly regression behavior. Test-only regressions can still be done by setting --compile=''. Compile-only regressions can be done by setting --test=''.
