Translator: prune `side_effect,noop` to `side_effect`
... if the result is unused. If `noop` includes a reference to a struct
that's entirely made of samplers, the transformation that removes
samplers from structs doesn't know what to do with the empty
expressions.

Translator: Fix sampler-in-struct when struct is unused
Standalone symbols as statements are also pruned. For example in the
below:
```
x;
g();
```
The line that only contains `x;` is pruned. In particular, this was
causing a bug with sampler-in-struct processing where the code ASSERTs
that if an instance of the struct is visited during traversal, that
it's already processed as part of an index chain (like s.member), but
in the above situation that is not true.

Translator: Work around tool paranoia w.r.t repeated std::move
An unknown diagnostic tool has flagged a usage in PruneNoOps, where an
empty vector is std::move'd on multiple iterations of a loop, as
error-prone. That was intended behavior. To silence the tool however,
the empty vector declaration is moved inside the loop.

Translator: Fix dead-code-elimination corner case
The DCE code had a corner case bug where a switch case containing
multiple DCE'ed `break`s followed by another case would cause some of
the DCE'ed statements in the first case to be doubly pruned, failing on
an assertion.
This was due to the fact that visitBlock() was asking traversal to
continue if a new case was visited while pruning nodes, but the
traversal does not take into account that some statements need to be
skipped and so would also visit the pruned statements. If the pruned
statements contain a branch instruction, they get re-pruned.
The visitBlock() function that does the pruning is reworked so that it
more clearly traverses the statements.

Translator: Prune trivial dead code
Code after discard, return, break and continue is discarded with this
change. This simplifies SPIR-V generation as no code is allowed after a
branch instruction and no special handling is necessary after this
change.

Translator: Allow tree validation in children of TCompiler
This is to be able to perform validation inside TranslatorVulkan, even
if it's through ASSERTs.
Additionally, every transformation is changed such that they do their
validation themselves. TIntermTraverser::updateTree() performs the
validation, which indirectly validates many of three tree
transformations. Some of the more ancient transformations that don't
use this function directly call TCompiler::validateAST.

Standardize copyright notices to project style
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.
