After we fall back from GlobalISel to SDAG, the verifier gets called, which calls getReservedRegs which uses SIMachineFunctionInfo::usesAGPRs which caches the result of UsesAGPRs. Because we have just fallen-back the function is empty and it incorrectly gets cached to false. This patch makes sure we don't try to run the verifier whilst the function is empty.
