Julia Suvorova 14120108f8 target/arm: Allow ARMv6-M Thumb2 instructions 
ARMv6-M supports 6 Thumb2 instructions. This patch checks for these
instructions and allows their execution.
Like Thumb2 cores, ARMv6-M always interprets BL instruction as 32-bit.

This patch is required for future Cortex-M0 support.

[PMM: move armv6m_insn[] and armv6m_mask[] closer to
 point of use, and mark 'const'. Check for M-and-not-v7
 rather than M-and-6.]
