  Log Message:
  -----------
  [VPlan] Use alloc-type to compute interleave group offset.

Use getAllocTypeSize to get compute the offset to the start of
interleave groups instead getScalarSizeInBits, which may return 0 for
pointers. This is in line with the analysis building the interleave
groups and fixes a mis-compile reported for
https://github.com/llvm/llvm-project/pull/106431.
