Change the handling of {dfv=} to a more general "braced constant"
expression, to be tagged with an instruction flag to make sure they
match the instruction in question.
This really ought to be an operand flag, but the opflags are precious;
as the CCMP/CTEST instructions can also take an immediate it probably
is necessary to invent a "special immediate" operand type that can
fold these together.
