C is the letter, and VALUE is a constant value.
Return 1 if VALUE is in the range specified by C.
HP-PA immediate field sizes:
5 bits: scalar/floating short loads + stores; deposit; conditional branch
11 bits: arithmetic immediate, compare immediate
14 bits: loads and stores; load offset
21 bits: load and add immediate long (but this isn't really used)
(there are also 13-bit and 26-bit immediates but only in system instructions)
`I' is used for the 11 bit constants.
`J' is used for the 14 bit constants.
`K' is used for values that can be moved with a zdepi insn.
