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.

Remove qualifiers from empty struct declarations in output
Empty struct declarations with qualifiers are rejected by NVIDIA GL
driver version 367.27. For example this kind of construct that is
expected to be accepted by the WebGL conformance tests is rejected:
const struct a {
int i;
};
Since qualifiers do not carry meaning unless a struct declaration
has declarators, they can be simply omitted from the translator
output in this kind of cases to work around this driver issue.
New unit test is added to check that pruning empty declarations works
correctly.
