[RISCV] Add OperandType to loadfpimm. (#114150)

topperc · web-flow · commit c62130f7b354 · 2024-10-29T19:42:35.000-07:00
This is represented in the MachineInstr and MCInst as a 5-bit unsigned
immediate so we use OPERAND_UIMM5. If someone needs to know for sure its
an FLI constant in the future we can break it out to a new type.
