More efficient version of Jul 10 bugfix of mine, as
discussed on egcs-patches.
* regclass.c (reg_scan_mark_refs): New arg min_regno. Only update
regscan information for REGs with numbers greater than or equal to
this. All callers changed.
(reg_scan_update): New function to efficiently update regscan
information on the fly.
* rtl.h: Add prototype.
* jump.c (jump_optimize): Call it when we make a transformation
which generates new pseudo-REGs.
