re PR debug/50299 (entryval: bigendian 32bit->64bit extension breaks address match)
PR debug/50299
* calls.c (load_register_parameters): Use use_reg_mode instead
of use_reg when adding a single register CALL_INSN_FUNCTION_USAGE
entry.
(expand_call): Set EXPR_LIST mode to TYPE_MODE of the argument
for stack CALL_INSN_FUNCTION_USAGE uses.
* expr.h (use_reg_mode): New prototype.
(use_reg): Changed into inline around use_reg_mode.
* expr.c (use_reg): Renamed to...
(use_reg_mode): ... this. Added MODE argument, set EXPR_LIST
mode to that mode instead of VOIDmode.
* var-tracking.c (prepare_call_arguments): Don't track parameters
whose EXPR_LIST mode is VOIDmode, BLKmode or X mode isn't convertible
to it using lowpart_subreg. Convert VALUE and REG/MEM to the
EXPR_LIST mode.
