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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182708 91177308-0d34-0410-b5e6-96231b3b80d8
