At the point where check_VecOperands()/VEX_check_operands() get run,
all other instruction attributes already matched, so any mismatch here
will tell the user more precisely what is wrong than using an eventual
(and very likely to occur) more generic error encountered on a
subsequent iteration through the template matching loop.

* config/tc-i386.c (match_template): New local variable
'specific_error'. Set it from i.error after failed
check_VecOperands or VEX_check_operands. Use it if set in
preference to i.error when actually issuing disagnostic.
