dEQP test 'dEQP-GLES3.functional.fbo.color.texcube.rgba32i' reaches assert in
nir_emit_alu() of fs_visitor.


$ INTEL_USE_NIR=1 ./deqp-gles3 -n
dEQP-GLES3.functional.fbo.color.texcube.rgba32i
dEQP Core 2014.x (0xcafebabe) starting..
  target implementation = 'Default'

Test case 'dEQP-GLES3.functional.fbo.color.texcube.rgba32i'..
deqp-gles3: brw_fs_nir.cpp:636: void fs_visitor::nir_emit_alu(nir_alu_instr*):
Assertion `__builtin_popcount(instr->dest.write_mask) == 1' failed.
Aborted

Disabling NIR passes the test.
