Hi!
This is something that has annyoed me for quite some time, but never got
around to do anything about it. The EXPR_LIST mode in
CALL_INSN_FUNCTION_USAGE never means the various REG_DEAD/REG_CFA* etc.
note names, always normal mode, so e.g. when one is looking for REG_CFA*
notes, the calls can confuse it, and when looking at calls, one has to
look up the REG_* values and convert them to enum machine_mode in the
debugger.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* print-rtl.c (in_call_function_usage): New var.
(print_rtx): When in CALL_INSN_FUNCTION_USAGE, always print
EXPR_LIST mode as mode and not as reg note name.
