[PATCH][AARCH64][5/5] Add macro fusion support for cmp/b.X for ThunderX

[Kyrill Tkachov]

Hi all,

Andrew posted this patch sometime ago (before stage1 closed) and I had 
rebased it on top of the
other macro fusion patches in that series.
This is a respin of that patch with the comment about not calling 
get_attr_type
repeatedly resolved 
(https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02251.html)

Tested aarch64-none-elf.

Is this ok to go in?

Thanks,
Kyrill
