Andrew Trick e7964c82c7 AArch64: Safely handle the incoming sret call argument. ... This adds a safe interface to the machine independent InputArg struct for accessing the index of the original (IR-level) argument. When a non-native return type is lowered, we generate the hidden machine-level sret argument on-the-fly. Before this fix, we were representing this argument as OrigArgIndex == 0, which is an outright lie. In particular this crashed in the AArch64 backend where we actually try to access the type of the original argument. Now we use a sentinel value for machine arguments that have no original argument index. AArch64, ARM, Mips, and PPC now check for this case before accessing the original argument.
