    AMDGPU: Fix an interaction between WQM and polygon stippling

    Summary:
    This fixes a rare bug in polygon stippling with non-monolithic pixel
shaders.

    The underlying problem is as follows: the prolog part contains the poly=
gon
    stippling sequence, i.e. a kill. The main part then enables WQM based on
the
    _reduced_ exec mask, effectively undoing most of the polygon stippling.

    Since we cannot know whether polygon stippling will be used, the main p=
art
    of a non-monolithic shader must always return to exact mode to fix this
    problem.
