Replace simple "if (cell-type)" with "else if" chain. Fix FIRRTL shift handling. Add support for parameterized modules, $shift, $shiftx. Handle default output file. Deal with no top module. Automatically run pmuxtree pass. Allow EXTRA_FLAGS and SEED parameters to be set in the environment for tests/tools/autotest.mk. Support FIRRTL regression testing in tests/tools/autotest.sh Add xfirrtl files to test directories to exclude files from FIRRTL regression tests that are known to fail.
