[PATCH] improve arm machine code (make -verify-machineinstrs happier)

[Quentin Colombet]

Hi Matthias,

I haven’t looked into the details of the patches but I have a general comment:
Could you add a test case for each case you are fixing (possibly in the same test file)?

Thanks for working on that.

Cheers,
-Quentin
