Add support for arrays of arrays in AST processing
Data concerning arrays of arrays is added in TType.
Parsing arrays of arrays and support for arrays of arrays in
TPublicType are still left to be implemented later.
ShaderVariable interface for arrays of arrays is also left to be
implemented later.
We rely on existing test coverage to make sure that arrays of arrays
are not accidentally exposed.

Set correct symbol ids when referring to GLSL built-ins
The symbol ids are fetched from the symbol table. A new utility
function is added to make this more convenient.

Reorganize AST traversal utility code
Define TIntermTraverser and TIntermLValueTrackingTraverser in a
separate header file. hash() function is moved out from
TIntermTraverser as it is not related to the core functionality
of traversing and transforming ASTs.
Also reorganize some traversers to follow common conventions:
- Intermediate output is now in OutputTree.h/.cpp
- Max tree depth check is now in IsASTDepthBelowLimit.h/.cpp

Clean up redundant initialization of gl_Position
In case gl_Position is statically used in the input shader, setting
the INIT_OUTPUT_VARIABLES flag will initialize gl_Position. Avoid
redundant initialization of gl_Position in this case.
Includes cleaning up memory management in InitOutputVariables_test:
all the pool-allocated variables will be freed at the end of each test
when the memory pool is cleared, so manual memory management is not
needed.
Also includes making the zero node check used in unit tests stricter
so that the tests are more reliable and moving it to
ShaderCompileTreeTest.h so that it can be reused in the future.

Propagate correct type to the lvalue in an output variable initializer
With the SH_INIT_OUTPUT_VARIABLES option enabled, vertex and fragment
shader outputs get initialized with zeros at the beginning of main.
However, previous to this patch the lvalues in the binary expression did
not receive the correct type. This can lead to incorrect modifications
of the AST in subsequent stages or incorrect output code from the
translator. The patch addresses the issue by copying the type
information from the symbol table.
