[LLVMdev] arm cortex-m3

[Bagel]

Now that there is good thumb2 support in the ARM backend, would someone 
please add "cortex-m3" to the "-march" list for the ARM backend.  This 
should produce pure thumb2 only code.  At some point, when the subsets 
are public, "cortex-m1" and "cortex-m0" should also be added.

thanks,
