[Mesa-dev] [PATCH 1/2] st/glsl_to_tgsi: fix block copies of arrays of doubles

[Nicolai Hähnle]

From: Nicolai Hähnle <nicolai.haehnle at amd.com>

Set the type of the left-hand side to the same as the right-hand side,
so that when the base type is double, the writemask of the MOV instruction
is properly fixed up.
