Look at TIntermLoop::traverse() in IntermTraverse.cpp, the control init part is not handled explicitly there (unlike the other two parts).  It is expected hat visitLoop will cover the init part.  The bug in the MapLongVariableNames is that the visitLoop doesn't do anything.  This CL fixes it.

After the shader compile (and before code output), the precision scopes are already lost.  In order to correctly output precisions, we need to emit precision in each variable declaration, therefore, each variable should have its precision set.  This CL fixes the bugs that the precisions are lost for variables using default precsions and struct fields.  Also, this CL fixes a bug in the grammar: constructors are not type_specifier and they shouldn't have precisions.

With this CL, we have the option to select a code output backend: GLSL, GLSL ES, or HLSL.

Note that we always emit the highest supported float precision for fragment shader due to anglebug 168.  Although this is a temporary solution, it's not against GLSL ES spec, because it's ok for implementation to upgrade precision.

Tested with WebGL conformance test suite, GLES2 conformance test suite (only failed 2/1198), and a few webgl demos, including worlds of webgl, aquarium, etc.

It turns out SetWindowLong succeeds for other threads in the same process but we do not want the WNDPROC to be called from threads other than the thread on which EGL is running on. This was one of the reasons --in-process-gpu was not working with ANGLE in Chrome.

It seems that DWM will, when given an HWND that has an associated
FlipEX swap chain, stretch the contents of the HWND to fill the new
window IF you don't issue draw calls to that HWND before the WM_PAINT
returns. This leads to horrendous sizing artifacts.

For Chromium, this is a show stopper.

But, FlipEx is definitely a good thing, for regular single process
applications.

So, is there a clean way to conditionally disable FlipEX for
these problem cases? The heuristic in this patch basically says "if your hwnd
is not in-process, then you're probably not painting in its HWND, so don't sue
FlipEX."

This catches the Chromium use case. There is still the possibility of a regular
single-process EGL application that tries to draw outside WM_PAINT that would
experience sizing artefacts. But, maybe that's OK.

Anyways, I'm not married to this technique. Just throwing something out there
to start the discussion. :)

Without this, sometimes the #line directive shows up at the end of
the previous line of shader source.  This was causing syntax errors
