[POWERPC] Handle alignment faults on SPE load/store instructions
This adds code to handle alignment traps generated by the following
SPE (signal processing engine) load/store instructions, by emulating
the instruction in the kernel (as is done for other instructions that
generate alignment traps):
evldd[x] Vector Load Double Word into Double Word [Indexed]
evldw[x] Vector Load Double into Two Words [Indexed]
evldh[x] Vector Load Double into Four Half Words [Indexed]
evlhhesplat[x] Vector Load Half Word into Half Words Even and Splat [Indexed]
evlhhousplat[x] Vector Load Half Word into Half Word Odd Unsigned and Splat [Indexed]
evlhhossplat[x] Vector Load Half Word into Half Word Odd Signed and Splat [Indexed]
evlwhe[x] Vector Load Word into Two Half Words Even [Indexed]
evlwhou[x] Vector Load Word into Two Half Words Odd Unsigned (zero-extended) [Indexed]
evlwhos[x] Vector Load Word into Two Half Words Odd Signed (with sign extension) [Indexed]
evlwwsplat[x] Vector Load Word into Word and Splat [Indexed]
evlwhsplat[x] Vector Load Word into Two Half Words and Splat [Indexed]
evstdd[x] Vector Store Double of Double [Indexed]
evstdw[x] Vector Store Double of Two Words [Indexed]
evstdh[x] Vector Store Double of Four Half Words [Indexed]
evstwhe[x] Vector Store Word of Two Half Words from Even [Indexed]
evstwho[x] Vector Store Word of Two Half Words from Odd [Indexed]
evstwwe[x] Vector Store Word of Word from Even [Indexed]
evstwwo[x] Vector Store Word of Word from Odd [Indexed]
