[PATCH] [AArch64] Select lower fsub, fabs pattern to fabd on AArch64

[Jyoti Allur]

Hi Karthik,
To further clarify, reason for clubbing the testcases of sadb, fabd into a single generic file is so that we can accomodate more patterns revolving around 
abs arithmetic, another reason being, adding more test files means running llc multiple times on each file, which in turn increases test time.
Hope this sounds reasonable.
