* cse.c (count_reg_usage): In a SET with a REG SET_DEST, count the
uses of the register in the SET_SRC. Remove unnecessary argument.
Replace it with this:
* cse.c (count_reg_usage): In INSN, JUMP_INSN and CALL_INSN cases,
if flag_non_call_exceptions is set and the insn may trap, pass
pc_rtx as dest for recursion.
In SET_SRC part of SET case, if dest is already set, pass it down
unchanged.

USEs of the stack slots to CALL_INSN_FUNCTION_USAGE.
