For ARM, shifts by immediate use a 5-bit constant, shifts by register
use the lower 8 bits of the register.
For ARMv6T2/ARMv7, bitfield instructions:
- BFC, BFI specify an immediate 5-bit starting bit position and
an immediate 5-bit ending bit position
- SBFX, UBFX specify an immediate 5-bit starting bit position
and an immediate 5-bit width.
