Functions to implement the FR (as in "free regs") type class.
For LLVM GHC calling convention (used registers), see https://github.com/llvm/llvm-project/blob/6ab900f8746e7d8e24afafb5886a40801f6799f4/llvm/lib/Target/RISCV/RISCVISelLowering.cpp#L13638-L13685

Get all free RealRegs (i.e. those where the corresponding bit is 1)
Set bits of all allocatable registers to 1
Set corresponding register bit to 1
Bitmaps to indicate which registers are free (currently unused)
The bit index represents the RegNo, in case of floating point registers with an offset of 32. The register is free when the bit is set.
