[PowerPC] Add Test for Paired Single Decoding

      

This has uncovered multiple bugs with my previous implementation, namely that
ps_res and ps_frsqte had the wrong opcode and that the decoding for
immediate-offset loads and stores in ps_l* and ps_st* caused internal compiler
errors.

      

I couldn't reuse the logic from other immediate-offset code because

1. The register and the offset field are not right next to each other
2. The currently existing memri* asm operands are not 12 bit with unaligned offsets.

This commit also fixes the test suite for powerpc as it puts the new
instructions into a separate namespace (called Paired).
