[FastISel][AArch64] Improve branch selection to support all FP conditions.

This adds the last two missing floating-point condition codes (FCMP_UEQ and
FCMP_ONE) also to the branch selection. In these two cases an additonal branch
instruction is required.

This also adds unit tests to checks all the different condition codes.

This is related o rdar://problem/18358882.
