Matt Arsenault bee2ad7185 AMDGPU/GlobalISel: Redo legality for build_vector 
It seems better to avoid using the callback if possible since
there are coverage assertions which are disabled if this is used.

Also fix missing tests. Only test the legal cases since it seems
legalization for build_vector is quite lacking.
