Hal Finkel bc2ee4c4e6 PPC: Combine duplicate (offset) lvsl Altivec intrinsics
The lvsl permutation control instruction is a function only of the alignment of
the pointer operand (relative to the 16-byte natural alignment of Altivec
vectors). As a result, multiple lvsl intrinsics where the operands differ by a
multiple of 16 can be combined.
