[PATCH, GCC][AArch64] Use Enums for code models option selection

Thu, 31 May 2012 02:56:52 -0700 

Hi,

This patch re-factors code models option selection in the AArch64 port:

 . Renaming variables such as mem_model to cmodel, for better clarity.
 . Using the generic support for enumerated option arguments.
 . Fixing touched code layout and formatting issues.

Thanks
Sofiane
