Tested with GLSL ES conformance suite (which doesn't test this) and
the WebGL conformance suite, which now contains tests to ensure that
these constructs compile correctly.

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.
