BFC clears a bitfield in a register. It clears width bits in Rd, starting at the low bit position lsb.
Other bits in Rd are unchanged.
BFI copies a bitfield into one register from another register. It replaces width bits in Rd starting at
the low bit position lsb, with width bits from Rn starting at bit[0]. Other bits in Rd are unchanged.
Do not use SP and do not use PC.
These instructions do not affect the flags.
