Rollup merge of #56599 - dlrobertson:fix_va_arg, r=eddyb
codegen: Fix va_list - aarch64 iOS/Windows ## Summary Fix code generated for `VaList` on Aarch64 iOS/Windows. ## Details According to the [Apple - ARM64 Function Calling Conventions]: > ... the type va_list is an alias for char * rather than for the struct > type specified in the generic PCS. The current implementation uses the generic Aarch64 structure for `VaList` for Aarch64 iOS. Switch to using the `char *` variant of the `VaList` and use the corresponding `emit_ptr_va_arg` for the `va_arg` intrinsic. Windows always uses the `char *` variant of the `VaList`. Update the `va_arg` intrinsic to use `emit_ptr_va_arg`.
