Guarantee that symbol nodes get unique ids
The code is refactored so that symbol nodes can only be initialized
with an unique id object. This prevents accidentally forgetting to
create an id for a symbol node.
This opens up possibilities for future optimization: For example the
names and types of symbols could be stored in a central location
inside the SymbolTable, and TIntermSymbol nodes would only need to
store the symbol id. The symbol id could be used to look up the name
and type of the node.

Refactor creating temporary symbols
This makes creating temporary symbols easy also outside of traversers.
This will be needed for improving variable initialization.

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.

Add gl_ViewportIndex to the symbol table
gl_ViewportIndex is a GLSL built-in that's needed to implement
instanced multiview. It is a bit of a special case: it only exists in
desktop GLSL and not ESSL, and it shouldn't be exposed to the parser.
We add a new level to the symbol table that's hidden from the parser
to make adding this kind of builtins in AST transforms consistent with
the way ESSL builtins are supported.

Clamp point size to maximum point size from the API on NVIDIA
NVIDIA OpenGL drivers have a bug where the point size range is being
reported incorrectly - it appears the core GL driver incorrectly gives
the range for smooth points, when it should be giving the range for
aliased points. Clamp the actual point size to the maximum point size
reported from the API so that the GLES spec is followed.
The same workaround seems to be necessary also on Android. The issue
was revealed by the trybots, and has not been fully diagnosed though.
The newly added test fails on AMD OpenGL.
As a part of this change, the existing tests in PointSpritesTest are
refactored to use gl_raii.
