[FastISel][AArch64] Fix load/store with frame indices.

At higher optimization levels the LLVM IR may contain more complex patterns for
loads/stores from/to frame indices. The 'computeAddress' function wasn't able to
handle this and triggered an assertion.

This fix extends the possible addressing modes for frame indices.

This fixes rdar://problem/18783298.
