re PR rtl-optimization/65401 (make_field_assignment broken for big-endian)

PR rtl-optimization/65401
* combine.c (rtx_equal_for_field_assignment_p): Add widen_x
argument.  If true, adjust_address_nv of x with big-endian
correction for the mode widening to GET_MODE (y).
(make_field_assignment): Don't do MEM mode widening here.
Use MEM_P instead of GET_CODE == MEM.

* gcc.c-torture/execute/pr65401.c: New test.
