Adding Bison and ANTLR grammars for GLSL ES. The grammars are derived

from the OpenGL ES specification and are intended to match the
structure in the spec as closely as possible while working with
existing tools. Hints were taken from the Mesa GLSL grammar, which
uses a custom parser generator, to solve reduce/reduce conflicts in
the Bison version. The grammars do nothing at the moment except parse
inputs and provide rudimentary error reporting. Follow-on work will
extend these grammars with the intended functionality. Basic testing
has been done but much more is needed.
