Committed r252121: <https://trac.webkit.org/changeset/252121>

The changes in https://trac.webkit.org/changeset/252121/webkit Broke several tests on iOS and introduced failing tests. 11 failing tests: webgl/1.0.3/conformance/extensions/get-extension.html webgl/1.0.3/conformance/extensions/oes-texture-float.html webgl/1.0.3/conformance/extensions/webgl-compressed-texture-size-limit.html webgl/1.0.3/conformance/extensions/webgl-draw-buffers.html webgl/1.0.3/conformance/glsl/misc/shader-with-reserved-words.html webgl/1.0.3/conformance/more/functions/readPixelsBadArgs.html webgl/1.0.3/conformance/more/functions/texImage2DHTML.html webgl/1.0.3/conformance/more/functions/texSubImage2DHTML.html webgl/1.0.3/conformance/renderbuffers/framebuffer-object-attachment.html webgl/1.0.3/conformance/textures/copy-tex-image-2d-formats.html webgl/1.0.3/conformance/textures/texture-npot-video.html History: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=webgl%2F1.0.3%2Fconformance%2Fextensions%2Fget-extension.html&test=webgl%2F1.0.3%2Fconformance%2Fextensions%2Foes-texture-float.html&test=webgl%2F1.0.3%2Fconformance%2Fextensions%2Fwebgl-compressed-texture-size-limit.html&test=webgl%2F1.0.3%2Fconformance%2Fextensions%2Fwebgl-draw-buffers.html&test=webgl%2F1.0.3%2Fconformance%2Fglsl%2Fmisc%2Fshader-with-reserved-words.html&test=webgl%2F1.0.3%2Fconformance%2Fmore%2Ffunctions%2FreadPixelsBadArgs.html&test=webgl%2F1.0.3%2Fconformance%2Fmore%2Ffunctions%2FtexImage2DHTML.html&test=webgl%2F1.0.3%2Fconformance%2Fmore%2Ffunctions%2FtexSubImage2DHTML.html&test=webgl%2F1.0.3%2Fconformance%2Frenderbuffers%2Fframebuffer-object-attachment.html&test=webgl%2F1.0.3%2Fconformance%2Ftextures%2Fcopy-tex-image-2d-formats.html&test=webgl%2F1.0.3%2Fconformance%2Ftextures%2Ftexture-npot-video.html&platform=ios

These two are also failing or timing out on Mac: webgl/1.0.3/conformance/textures/texture-npot-video.html webgl/1.0.3/conformance/glsl/misc/shader-with-reserved-words.html

webgl/1.0.3/conformance/context/context-release-upon-reload.html seems flaky, in https://ews-build.webkit.org/#/builders/17/builds/5817 , it passed in layout-tests step, but failed in re-run-layout-tests step.
