  Add a helper class for compiler string matching tests
  
  The MatchOutputCodeTest class makes it easier to implement tests that
  do string matching on compiler output. Inheriting test classes set the
  compiler settings, tests then call compile() with the shader string
  and can call foundInCode() to check if the output code contains a
  given string.
  
  Various compiler unit tests that already did string matching are
  refactored to make use of this new helper class. Some tests now use
  SH_GLES3_SPEC instead of SH_GLES2_SPEC - this should not have a
  significant impact on test coverage.
  
  Some compileTestShader function variants that are now unused can be
  removed from the code.
