I don't need a gcc expert for that :) Since you can specify the size
in the machine description, it's not a problem at all. Currently, there
are RTL terms like

	(match_operand:SI 2 "regimm8_operand" "r,i")

which refer to the C function regimm8_operand() - if you modify that
to accept only 6-bit operands, you're done (for ALL instructions that
can use this kind of operand). Everything that doesn't fit will be
loaded into a register.
