[AArch64] Reject invalid immediate operands to MSR UAO
In the instruction to write to the ARMv8.2 PSTATE field UAO,
MSR UAO, #<imm>, the immediate should be either 0 or 1 but GAS accepts
any unsigned 4-bit integer.
This patch implements the constraint on the immediate, generating an
error if the immediate operand is invalid, and adds tests for the
illegal forms.
