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.

Promote and fold indexing nodes similarly to other binary ops
Indexing nodes now get their type set in TIntermBinary::promote, same
as math and logic ops. They are also constant folded through
TIntermBinary::fold() instead of having special functions for constant
folding them in ParseContext.
Index nodes for struct and interface block member access now always
have integer type, instead of sometimes having the type of the field
they were used to access.
Usage of TIntermBinary constructor is cleaned up so only the
constructor that takes in left and right operands is used. The type
of TIntermBinary nodes is always determined automatically.
Together these changes make the code considerably cleaner.
Note that the code for constant folding for array indexing is actually
never hit because constant folding array constructors is still
intentionally disabled in the code.

Support writing initializers using HLSL literal syntax
Instead of using constructor functions to initialize variables, it is
better to use literal initializer syntax provided by HLSL when it is
possible. This way shader complexity is reduced and constant array
initialization doesn't have to go through as many AST transformations.
Before this patch, vec4 initialization would result in the following
kind of HLSL:
float4 f = float4(1.0, 2.0, 3.0, 4.0);
After this patch, it will be:
float4 f = {1.0, 2.0, 3.0, 4.0};
Before this patch, vec2 array initialization would result in the
following kind of HLSL:
float2 f[2] = {0, 0, 0, 0};
angle_construct_into_2_float2(f, float2(1.0, 2.0), float2(3.0, 4.0));
After this patch, it will be:
float2 f[2] = {1.0, 2.0, 3.0, 4.0};

Accept const array initialization in shader parsing
Array constructors are not folded, unlike all other constant expressions.
Change initializer parsing path so that it accepts constant initializers
whether they are folded or not.
Some parts need to be adapted to work with expressions that are qualified
as constant but that are not necessarily folded:
1. Identifier parsing
2. Indexing parsing
3. Field selection parsing
4. HLSL output for variable declarations
5. Determining unary operator result type
6. Determining binary operator result type
7. Determining built-in function call result type
8. Determining ternary operator result type
Corner cases that are not supported yet:
1. Using array constructors inside case labels
2. Using array constructors inside array size expressions
3. Detecting when a negative constant expression containing an array
constructor is used to index an array
In these cases being able to constant fold the expression is essential to
validating that the code is correct, so they require a more sophisticated
solution. For now we keep the old code that rejects the shader if ANGLE
hasn't been able to constant fold the case label or array size. In case of
indexing an array with a negative constant expression containing an array
constructor, ANGLE will simply treat it as a non-constant expression.

Support array initialization in HLSL output
Do this by separating each array initialization into a declaration and an
assignment. Array assignment is already supported in HLSL output by replacing
it with a function call.
The functionality is tested by the struct array constructor tests in dEQP.
