[llvm] r239805 - Disable llvm/test/CodeGen/MIR/machine-function.mir on x86 msc18 for now. Investigating.

[Alex L]

Thanks, I missed this.

I think the emitted MIR differs from the input MIR because the optional
attributes like exposesReturnTwice, etc. aren't specified in the first two
functions. The YAML input class should set them those attributes to default
values for that type, as specified in LLVM's YAML documentation. But this
isn't happening here for some reason.

I think the Yaml Input class has a bug where it doesn't actually initialize
the optional values, so hopefully fixing that should solve the problem.

Alex.
