Comment (by singpolyma):

 includes/stg/MachRegs.h contains information for arm, and
 compiler/codeGen/CodeGen/Platform/ARM.hs says to use it, but
 includes/CodeGen.Platform.hs does not mention MACHREGS_arm anywhere, and
 does not have the register-name-to-indices #defines present.  I'm not sure
 what the index values are supposed to be in this case, so I'm not sure how
 to proceed.
