Summary: A new function pass (Transforms/CFGuard/CFGuard.cpp) inserts CFGuard checks on indirect function calls, using either the check mechanism (X86, ARM, AArch64) or or the dispatch mechanism (X86-64). The check mechanism requires a new calling convention for the supported targets. The dispatch mechanism adds the target as an operand bundle, which is processed by SelectionDAG. Another pass (CodeGen/CFGuardLongjmp.cpp) identifies and emits valid longjmp targets, as required by /guard:cf. This feature is enabled using the `cfguard` CC1 option.
