Jesse Natalie 97b6ea71a0 microsoft/compiler: Add a pass for hull and domain shaders to shrink tess level vars
DXIL validation will complain if the tess factor signature entries have the
wrong number of components for the shader's domain. Make sure that both
hull and domain shaders have the right number, and drop loads and stores
from the removed components.
