[PATCH] [ARM] Be Conservative when coalescing into SP

[Matthias Braun]

I just looked at the ARM instruction definitions and it seems that the T2I_bin_ii12rs multiclass used for SUB has a no-SP restriction (it is using the rGPR class instead of GPRnopc) but on the Rm input instead of the Rn input, maybe this is simply a specification typo?
