  Revert "Add pragma errors for malformed pragmas."
  
  Since this commit was made, dEQP tests were fixed to check that
  unrecognized pragma tokens only generate warnings, not errors.
  
  This applies to both ESSL1.00 and ESSL3.00, which specify this
  behavior in section 3.4 Preprocessor.

  This reverts commit d3c29f57aaeb451b149bbb9fd17b3f1f99101c52.
