Re^5-land "Move Uniform and UBO info to the gl::Program layer."

This data was previously stored entirely in the Impl level. Move
as much as possible to the GL level, using a read-only view in the
Impl level. Some information in D3D-specific, and should be stored
separately in the Impl.

This patch has a lot of refactoring that splits the D3D and GL info,
and moves as much validation as possible to the GL layer, where it
is shared between the back-ends.

Re-land with fix for dEQP unused uniforms. The fix involves storing
a local copy of all uniform data in the GL layer. This will also
let us validate sampler indexes during draw calls at the GL layer.

Re-re-land with a fix for multiply defined symbols on Clang.

Re-re-re-land with a fix for boolean uniforms and Uniform{1234}f.

Re^4-land with a fix for boolean uniform arrays and UBO uniforms.

Re^5-land with a fix for a test warning on Linux.

#ANGLE The goal of ANGLE is to allow Windows users to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to DirectX 9 or DirectX 11 API calls.

ANGLE is a conformant implementation of the OpenGL ES 2.0 specification that is hardware‐accelerated via Direct3D. 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. Work on ANGLE's OpenGL ES 3.0 implementation is currently in progress, but should not be considered stable.

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.
