this isn't done (the majority), delete md_relax_table altogether.
For machines with WORKING_DOT_WORD, delete md_{short,long}_jump_size.
(md_relax_table): No longer const. Add PCINDEX entries.

new PCINDEX modes.

insertion routines cannot be used (they don't do anything and we're
using implicit addends now so we need to output something).
* config/tc-arc.h (FAKE_LABEL_NAME): Define.
unsigned seemingly negative number. Don't bother shifting a zero
value.
(mips_ip): For case 'j', if there are more alternatives, and the
ISA level is at least 3, don't accept an unsigned seemingly
negative number.

(write_object_file): Don't treat h8300 and z8k specially with regard to fixups.
* config/tc-h8300.c (md_begin): Set linkrelax.

than the current machine type, then update the current machine
type.
