Tim Northover 7bf2e1b9ef Check whether MCInst operand isImm before calling getImm.
When processing possible aliases, TableGen assumes that if an operand *can* be
an immediate, then it always *will* be. This is incorrect for the AArch64
backend. This patch inserts a check in the generated code to make sure isImm is
true first.
