translator: Scope all classes with "sh".
I was seeing an odd problem with our PoolAlloc conflicting with the
glslang/Vulkan TIntermNode, so the fix was to move everything to a
separate namespace.
The bison grammars are also regenerated. No functional changes.

Split TIntermDeclaration from TIntermAggregate
The new class TIntermDeclaration is now used for struct, interface
block and variable declarations. TIntermDeclaration nodes do not have
a type - rather the type is stored in each child node. The types may
differ in case the declaration is a series of array declarators with
mismatching sizes.
TIntermAggregate is still used for function calls, function
prototypes, function parameter lists and invariant declarations.

Split TIntermBlock from TIntermAggregate
The new TIntermBlock node class replaces TIntermAggregate nodes with
the EOpSequence op. It represents the root node of the tree which is
a list of declarations and function definitions, and any code blocks
that can be denoted by curly braces. These include function and loop
bodies, and if-else branches.
This change enables a bunch of more compile-time type checking, and
makes the AST code easier to understand and less error-prone.
The PostProcess step that used to be done to ensure that the root node
is TIntermAggregate is removed in favor of making sure that the root
node is a TIntermBlock in the glslang.y parsing code.
Intermediate output formatting is improved to print the EOpNull error
in a clearer way.
After this patch, TIntermAggregate is still used for function
definitions, function prototypes, function parameter lists, function
calls, variable and invariant declarations and the comma (sequence)
operator.

Make UnfoldShortCircuit to change AST instead of writing output
This is needed to make way for further AST transformations to handle array
expressions that need to work correctly together with unfolding short-
circuiting operators. This also improves the maintainability of HLSL output
by isolating the unfolding into a separate compilation step.
The new version of UnfoldShortCircuit traverser will traverse the tree until
an expression that needs to be unfolded is encountered. It then unfolds it and
gets reset. The traverser will be run repeatedly until no more operations to
unfold are found. This helps with keeping the traverser's design relatively
simple.
All declarations are separated to single declarations before short-circuit
unfolding is run. Previously OutputHLSL already output every declaration
separately.

Put each array declarator into a separate declaration in HLSL output
Since HLSL doesn't support arrays as l-values, HLSL output needs to split
declarators that initialize arrays to variable declaration and assignment
implemented via a function call. To prepare for this, it is necessary that each
declarator has its own declaration.
