Kumar Gala 26caeb2ee1 [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]
