ES31: Implement gl_in in Geometry Shader
This patch intends to implement geometry shader built-in interface
block instance gl_in defined in GL_OES_geometry_shader.
1. Add the definition of gl_in and its interface block gl_PerVertex
into the symbol table.
2. Support gl_Position as a member of gl_in.
3. Set the array size of gl_in when a valid input primitive type is
known.
4. Add check that it should be a compile error to index gl_in or
call length() on gl_in without a valid input primitive declaration.
This patch also adds unit tests to cover all these new features.
