Juergen Ributzka 06640d93e0 [FastISel][AArch64] Add support for frameaddress intrinsic.
This commit implements the frameaddress intrinsic for the AArch64 architecture
in FastISel.

There were two test cases that pretty much tested the same, so I combined them
to a single test case.

Fixes <rdar://problem/17811834>
