  [SVE] Fix getAlignmentInfo for scalable vectors

When calculating the natural alignment for scalable vectors it
is acceptable to calculate an allocation size based on the minimum
number of elements in the vector.

This code path is exercised by an existing test:

  CodeGen/AArch64/sve-intrinsics-int-arith.ll
