[Mesa-dev] [PATCH 2/4] tgsi: (trivial) fix handling msaa resources on TXF

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

Just handle as ordinary 2d / 2d array resources. Prevents an assertion failure
with softpipe and piglit glsl-resource-not-bound 2DMS/2DMSArray tests.
While here also fix TXD shadowCube similarly, which fixes the crash with piglit
tex-miplevel-selection textureGrad CubeShadow (the test will still fail due to
softpipe being broken).
