Description
When `OpImageQuerySizeLod` and `OpImageSampleImplicitLod` are used on the same texture a dummy `sampler2D` is created when there is no need to.

Research direction
No file, test, or entry point is named. Start by reproducing the GLSL output for shaders using OpImageQuerySizeLod and OpImageSampleImplicitLod on the same texture, then trace sampler creation in the relevant SPIRV-Cross compiler path; done means the unnecessary dummy sampler is no longer emitted.
