gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables. That's OK, but not best
practice. tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.
