Ensure aux-target specific builtins get validated. I discovered that when using an aux-target builtin, it was recognized as a builtin but never checked. This patch checks for an aux-target builtin and instead validates it against the correct target. It does this by extracting the checking code for Target-specific builtins into its own function, then calls with either targetInfo or AuxTargetInfo.

Fix aux-target diagnostics for certain builtins When I fixed the targets specific builtins to make sure that aux-targets are checked, it seems I didn't consider cases where the builtins check the target info for further info. This patch bubbles the target-info down to the individual checker functions to ensure that they validate against the aux-target as well. For non-aux-target invocations, this is an NFC.
