PR82317: S/390: Fix vec_min/vec_max builtins for IBM z13.
With IBM z14 a hardware instruction for floating point min and max has
been added while for IBM z13 we emulated min/max for vector double with
compare and select. This testcase makes sure that we fall back to the
emulated variant when compiling for z13.
