* function.c (assign_parms): For data.passed_pointer parms
use MEM of data.entry_parm instead of data.entry_parm itself
as DECL_INCOMING_RTL.
* dwarf2out.c (rtl_for_decl_location): Use DECL_INCOMING_RTL
also when passed and declared mode is the same, DECL_RTL
is a MEM with pseudo as address and DECL_INCOMING_RTL is
a MEM too.
