IRGen: Call SetLLVMFunctionAttributes{,ForDefinition} on __cfi_check_fail. This has the main effect of causing target-cpu and target-features to be set on __cfi_check_fail, causing the function to become ABI-compatible with other functions in the case where these attributes affect ABI (e.g. reserve-x18). Technically we only need to call SetLLVMFunctionAttributes to get the target-* attributes set, but since we're creating a definition we probably ought to call the ForDefinition function as well. Fixes PR44094. Differential Revision: https://reviews.llvm.org/D70692
