can't handle, mark it unrenameable instead. For terminate_write,
terminate chains that are written with an exact match or a superset
of registers. Set fail_current_block if multi-word lifetimes are too
complex to handle.

Rearrange the steps so that earlyclobbers are noted before reads
are processed. Add new steps to keep track of hard register lifetimes
