Modified the sched_macro_fuse_insns() as required.

Done. Pushed the check into target macros.

The modifications were generic and and quite different from ALU+BRANCH
fusion; a separate patch is posted with the above 2 modifications at:-
https://gcc.gnu.org/ml/gcc-patches/2017-03/msg01368.html

Added to check that same registers are used in ALU and Branch instruction.

Bootstrapped and Regression tested on AArch64.

Please review the patch and let us know if its okay?
