Improve info log length checks
Extend the info log length checks to shader_utils used by tests, and
treat info log with length 1 as empty, since it can only include the
null terminator. At least the Intel GL driver may generate "\0" as
info log in some situations, for example when compiling a user-defined
function with 50000 parameters.

Program/ShaderGL: handle empty info logs
The GL driver can sometimes have an empty info log and return an info
log length of 0. This would cause a vector to be initialized with a
length of 0 just before it's .data() pointer was used, causing a
segfault.

Don't ASSERT shader compilation success in ShaderGL.
This assertion was useful for debugging the initial implementation but it
is becoming an issue in tryjobs where tests will hang instead of fail due
to driver bugs.

Fix debug annotations and shaders.
The Program refactor inadvertantly broken Debug annotations. Fix this
by correctly passing the path to the temporary shader source in the
first "C" string argument to ShCompile, instead of as the first part
of the source string.

compiler: Rewrite do-while loops as while loops
This works around a Mac driver shader compiler bug that makes many
do-while loops cause GPU-hangs when ran.

Remove rx::ShaderSh and move the shared code to the GL.
The GL layer can interact with the translator directly, to query all
the active shader variables and call ShCompile.

Make a shader Shader::Data state structure.
This design follows the similar designs for Program, Framebuffer, etc.
Because of the current design, share a mutable pointer with the Impl
so the patch becomes a bit smaller and easier to review. In a follow-
up patch we can move the shared code into the GL layer.

This class uses no Impl-specific code. We can also do a similar
code relocation for the gl::Shader class, but in several steps
because it is a bit more complex.

Make output variables part of Program's shared data.
Also initialize this structure within Program instead of DynamicHLSL.
This should have benefits for other back-ends. Also these variables
weren't being serialized and de-serialized with the program binary,
which could mess up WebGL apps that use MRT.
