Joerg Sonnenberger 002a14765e Enabling thumb2 mode used to force support for armv6t2. Replace this 
with a temporary assertion and adjust the various test cases.

Jim Grosbach cf1464d943 ARMv7M vs. ARMv7E-M support. 
The DSP instructions in the Thumb2 instruction set are an optional extension
in the Cortex-M* archtitecture. When present, the implementation is considered
an "ARMv7E-M implementation," and when not, an "ARMv7-M implementation."

Add a subtarget feature hook for the v7e-m instructions and hook it up. The
cortex-m3 cpu is an example of a v7m implementation, while the cortex-m4 is
a v7e-m implementation.
