	In glsl the clamp function has undefined behavior when min > max. For the clamp node this resulted in differences between cycles and eevee. This patch adds the expected implementation for minmax. The old clamp function is still used in cases where we know for certain that the input values are correct (math node clamp option). GPU uses optimized code and silicon in these cases.

	Modes: Linear interpolation (default), stepped linear, smoothstep and smootherstep. This also includes an additional option for the Clamp node to switch between Min Max (default) and Range mode. This was needed to allow clamping when To Max is less than To Min. Reviewed By: JacquesLucke, brecht Differential Revision: https://developer.blender.org/D5827
2019-08-30	GPU: Split gpu_shader_material into multiple files.	OmarSquircleArt
	This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch. Reviewers: brecht Differential Revision: https://developer.blender.org/D5616
