            Bug ID: 37310
           Summary: [TableGen] Add more checks to the subtarget emitter to
                    validate scheduling information.

Some scheduling information makes no sense but makes it through the
SubtargetEmitter without any warnings. We should add more validation.
Stuff that makes absolutely no sense should trigger fatal errors.

One example I stumbled upon is inconsistencies in resource units vs resource
cycles: The cycles are optional and default to all ones, opening up to various
miserpretations by the developers that are not caught at compile time. This
happens at least on Arm/AArch64 and X86.
