-/* The letters I, J, K, L and M in a register constraint string
- can be used to stand for particular ranges of immediate operands.
- This macro defines what the ranges are.
- C is the letter, and VALUE is a constant value.
- Return 1 if VALUE is in the range specified by C.
-
- bfin constant operands are as follows
-
- J 2**N 5bit imm scaled
- Ks7 -64 .. 63 signed 7bit imm
- Ku5 0..31 unsigned 5bit imm

- Ku3 0 .. 7 unsigned 3bit imm
