+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 polygon
+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 part
+of a non-monolithic shader must always return to exact mode to fix this
+problem.
