Jamie Madill f939cb63fd Revert "Reland "Add more test_utils functions."" 
This reverts commit 7923e234bc.

Reason for revert: Fails compilation on rollers:

    [2097/6048] SOLINK ./lib_angle_unittests__library.cr.so
    FAILED: lib_angle_unittests__library.cr.so lib_angle_unittests__library.cr.so.TOC lib.unstripped/lib_angle_unittests__library.cr.so
    python "../../build/toolchain/gcc_solink_wrapper.py" --readelf="../../third_party/android_ndk/toolch...(too long)

Original change's description:
> Reland "Add more test_utils functions."
> 
> This is a reland of 5fcfcea4a9
> 
> Re-land uses static linking with angle_util. The root cause
> of the CFI error wasn't solved. Static linking works around
> the problem by not using any export rules.

ANGLE - Almost Native Graphics Layer Engine

The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
