Matt Turner	8e2b8bd0e6	glsl: Set proper swizzle when a channel is missing in vectorizing. ... Previously, for example if the x channel was missing from a series of assignments we were attempting to vectorize, the wrong swizzle mask would be applied. a.y = b.y; a.z = b.z; a.w = b.w; would be incorrectly transformed into a.yzw = b.xyz; Fixes two transform feedback tests in the ES3 conformance suite.
