[AArch64] Reject invalid immediate operands to MSR PAN
The support for accessing the ARMv8.1 PSTATE field PAN allows
instructions of the form MSR PAN, #<imm> with <imm> any unsigned 4-bit
integer. However, the architecture specification requires that the
immediate is either 0 or 1.
This patch implements the constraint on the immediate, generating an
error if the immediate operand is invalid, and adds tests for the
illegal forms.
