[PATCH][AARCH64]Fix syntax error in target selector "-O2" for volatileloadpair-1.c & volatileloadpair-2.c

[Renlin Li]

Hi all,

This is a simple fix to correct two typos (I believe) in the newly 
introduced volatileloadpair-1.c & volatileloadpair-2.c test case.

After the change, the test cases compiles and runs correctly.
Okay to commit?

Regards,
Renlin Li
