[PATCH][ARM][5/n] Partial IT block deprecation in ARMv8 AArch32 - load/store multiple

[Kyrylo Tkachov]

Hi all,

This patch updates the fixed-point math patterns in arm-fixed.md to
conform to new IT block rules in ARMv8. The add/sub instructions can be
placed in an IT block if they use the low registers.
The other more exotic variants (ssub, uqadd etc) do not have 16-bit
encodings and can therefore not be conditionalised by the new rules.

Tested together with the other patches in the series by bootstrap on a
Cortex-A15 and regtest arm-none-eabi on qemu and model.

Ok for trunk?


Thanks,
Kyrill
