ppc: Fix signal delivery in ppc-user and ppc64-user
There were a number of bugs in the implementation:
- The structure alignment was wrong for 64-bit.
- Also 64-bit only does RT signals.
- On 64-bit, we need to put a pointer to the (aligned) vector registers
in the frame and use it for restoring
- We had endian bugs when saving/restoring vector registers
- My recent fixes for exception NIP broke sigreturn in user mode
causing us to resume one instruction too far.
- Add VSR second halves
