glsl: Parse shared keyword for compute shader variables
v2: * Move shared parsing under storage qualifiers (tarceri) * Fail to compile if shared is used in non-compute shader (tarceri) * Use separate shared_storage bit for shared variables (tarceri) Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
