ARM: Don't rely on undefined behavior to get arithmetic right shift.
...
Shifting to the right of a signed value when the MSB is one is technically
undefined behavior, even though in my experience it's done the "right thing"
and sign extended the value. This replaces the arithmetic right shift code in
ARM that uses that coincidence with some code that relies on bit math.

ARM: Restrict the shift amount from a register to 8 bits.
...
The shift amount when taken from a register is supposed to be truncated to an
8 bit value.
