For all "ANGLE Project" copyrights, standardize to the format specified
by the style guide. Changes:
- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
  initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
  "The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by
templates.

Traversers used during parsing can be vulnerable to stack overflow
since the AST has not yet been validated for max depth. Make sure to
check for traversal depth in traversers used during parsing.
We set the maximum traversal depth in ValidateGlobalInitializer and
ValidateSwitchStatementList to 256, which matches the default value
for validating general AST complexity. The depth check is on
regardless of compiler options. In case the traversers go over the
maximum traversal depth, they fail validation.

The GLSL ES 3.00.6 spec is a bit unclear on this, but it does disallow
case statements "inside control flow". GLSL ES 3.10 clarifies this and
disallows any nesting of case or default labels within other
statements.

No statement should be required after the last case label of a switch
statement in ESSL 3.10. The validation is still kept for ESSL 3.00 for
dEQP compatibility. If the dEQP tests are changed in the future, we
might consider just issuing a warning regardless of shader version.

              |   | 923ecef6 | 2017-10-11T12:01:38 |  | Fix switch statement validation corner cases
The grammar needs to generate AST nodes even for no-op statements,
since they might be the last statement in a switch statement that is
required for switch statement validity. Change the grammar to generate
nodes from empty blocks and empty declarations.
We also need to do some further processing of the AST. This is because
PruneEmptyDeclarations will still remove empty declarations, and at
least the NVIDIA driver GLSL compiler doesn't accept some types of
no-op statements as the last statement inside a switch statement. So
after parsing has finished we do rudimentary dead code elimination to
remove dead cases from the end of switch statements.

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.

Ternary operator nodes are typed parts of expressions, they always
have two children and the children are also guaranteed to be
TIntermTyped. "If" selection nodes can't be a part of an expression,
they can have either one or two children and the children are code
blocks. Due to all of these differences it makes sense to store these
using two different AST node classes.

-No statement between a label and the end of a switch statement
-Statements in a switch statement before the first case statement
-Mismatch between the type of init-expression and type of a case label
-Case or default label nested inside other control flow nested within the
corresponding switch
Tested by manually disabling shading language version checks for switch
and by manually enabling case statements in a Chromium build and checking
that the expected errors are generated.
