S/390: Fix the vec_xl / vec_xst style builtins
This patch fixes several problems with the vec_xl/vec_xst builtins:
- vec_xl/vec_xst needs to use the alignment of the scalar memory
operand for the vector type reference. This is required to emit the
proper vl/vst alignment hints.
- vec_xl / vec_xld2 / vec_xlw4 should accept const pointer source operands
- vec_xlw4 / vec_xstw4 needs to accept float memory operands
