glsl: Pass struct shader_compiler_options into do_common_optimization.

do_common_optimization may need to make choices about whether to emit
certain kinds of instructions.  gl_context::ShaderCompilerOptions
contains exactly that information, so it makes sense to pass it in.

Rather than passing the whole array, pass the structure for the stage
that's currently being worked on.
