One question I can't answer and I think would need wider review, is whether 
this is type of material (common options for specific CPUs) is suited for the 
Clang Documentation or whether it would be better hosted by Arm itself, for 
example on developer.arm.com? I think that a more reference like Arm CPU 
options like https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html would work 
better in the Clang documentation.

I think the material is useful, especially for people new to these CPUs.

-mfloat-abi=hard -mthumb

----------------
I think you mean arm-arm-none-eabi for an upstream triple selecting the 
bare-metal driver?
