[PATCH][ARM][7/n] Partial IT block deprecation in ARMv8 AArch32 - straightforward arm.md changes

[Kyrylo Tkachov]

Hi all,

This patch adjusts a number of patterns in arm.md for the IT block rules
in -mrestrict-it. The changes are mostly straightforward, disabling the
cond_exec version for -mrestrict-it in some cases and adding
alternatives that can produce a 16-bit encoding in others.

Bootstrapped on Cortex-A15 and tested arm-none-eabi on a model on
armv7-a and armv8-a architecture levels.

Ok for trunk?

Thanks,
Kyrill
