[obish] Delete PARM_BOUNDARY

- Subject: [obish] Delete PARM_BOUNDARY
Hello,
Other posts drew my attention to this:
- PARM_BOUNDARY is only used by push_value
- push_value is only used by legacy_push_arguments.
- legacy_push_arguments is only used when push_dummy_call isn't supplied
yet:
- only m68k sets PARAM_BOUNDARY
- m68k sets (as of recent changes) push_dummy_call
hence PARM_BOUNDARY is dead.
baring comments I'll commit this in a day or so,
Andrew
* gdbarch.sh (PARM_BOUNDARY): Delete.
gdbarch.h, gdbarch.c: Re-generate.
* valops.c (PARM_BOUNDARY): Delete macro.
(value_push): Delete PARM_BOUNDARY code.
* m68k-tdep.c (m68k_gdbarch_init): Do not set parm_boundary.
