        Inconsistent failure modes from uniform[Matrix]* with null WebGLUniformLocation
        https://bugs.webkit.org/show_bug.cgi?id=36574

        Fixed bugs in JavaScript bindings for uniform[Matrix]* entry
        points causing them to throw exceptions rather than synthesize GL
        errors. Fixed the implementations to synthesize INVALID_VALUE
        rather than INVALID_OPERATION to comply to the WebGL spec. Updated
        uniform-location-expected.txt to incorporate the correct error.
        Tested in Safari and Chromium.
