[PATCH, ARM][10/n] Split scc patterns using cond_exec


This patch converts define_insn into define_insn_and_split to split
some alternatives of movsicc_insn and some scc patterns that cannot be
expressed using movsicc. The patch emits cond_exec RTL insns.

Tested as part of the series for splitting arm.md patterns that output
multiple asm instructions.

Ok for trunk?
