powerpc: Don't handle ALTIVEC/SPE in ASM in _switch(). Do it in C.
_switch() saves and restores ALTIVEC and SPE status.
For altivec this is redundant with what __switch_to() does with
save_sprs() and restore_sprs() and giveup_all() before
calling _switch().
Add support for SPI in save_sprs() and restore_sprs() and
remove things from _switch().
