  Add support for ES31 context creation
  
  The dEQP test for context creation passes.
  
  SH_WEBGL3_SPEC has been added, but it should be considered whether we
  should keep it, remove it or rename it. It was added so that there is
  a webgl mapping to es 310 shaders. Check Compiler.cpp. The bison file
  has been modified so that some tokens from es3 can be also used in
  es31 as well.
  
  A separate macro ES3_1_ONLY is added so that some tokens are limited
  only for es 310 shaders.
