radeonsi: add a standalone compiler amdgcn_glslc
This will be used by GLSL lit tests. For developers only. It shouldn't be distributable and it doesn't use the Mesa build system. Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>

+/**
+ * This program reads and compiles multiple GLSL shaders from one source file.
+ * Each shader must begin with the #shader directive. Syntax:
+ * #shader [vs|tcs|tes|gs|ps|cs] [name]
+ *
+ * The shader name is printed, followed by the stderr output from
+ * glCreateShaderProgramv. (radeonsi prints the shader disassembly there)
+ *
+ * The optional parameter -mcpu=[processor] forces radeonsi to compile for
+ * the specified GPU processor. (e.g. tahiti, bonaire, tonga)
+ *
+ * The program doesn't check if the underlying driver is really radeonsi.
+ * OpenGL 4.3 Core profile is required.
