* valops.c (hand_function_call): Align the initial stack pointer
and STRUCT_ADDR using frame_align. When STRUCT_RETURN and
FRAME_ALIGN_P, use STRUCT_ADDR to obtain the called function's
return value.
* mips-tdep.c (mips_frame_align): New function.
(mips_gdbarch_init): Set frame_align.
* gdbarch.sh (FRAME_ALIGN): New method.
* gdbarch.h, gdbarch.c: Re-generate.
