[Patch, aarch64 1/2] aarch64: Additional interface function implementation

[Ajit Agarwal]

Hello All:

Common infrastructure using generic code for pair mem fusion of different
targets.

Implements additional interface virtual function implementation
required for rs6000 target.

Tested for aarch64-linux-gnu.

Thanks & Regards
Ajit
