Subject: [Patch, ARM][11/n] Split patterns that output multiple assembly instructions - thumb2.md

This patch continues to clean up patterns that output multiple assembly
instructions. It handles most of the patterns in thumb2.md. 

The following patterns are not split:
  thumb2_movcond, thumb2_cond_move - complex, maybe later.
  tls_load_dot_plus_four - won't split: uses asm_out in output statement.
  thumb2_cbz - won't split: uses pc in length attribute and length in output
statement.
  thumb2_cbnz - likewise.

No regression on qemu for arm-none-eabi. Bootstrap successful on Cortex-A15.

Ok for trunk?

Thanks,
Greta
