SymbolTable::New() used to build and return a symbol without a registered name. When you asked for the name of the symbol it would return tint_symbol_N, where N is the numerical identifier for the symbol.
This approach was a major tripping hazzard for transforms that liked to fetch the source program name, and register it in the new program (in this situation, you should always use `CloneContext::Clone(Symbol)`).
Without special casing for unnamed symbols, you could end up promoting the unnamed symbol to a named symbol, and then colliding against a new unnamed symbol.
This is exactly what happened in tint:711.
Instead, with this change:
* The concept of unnamed symbols has been removed. All symbols now have a name.
* The signature of `SymbolTable::New()` has been changed to take a name parameter (which defaults to 'tint_symbol'). This can be used to create a new, unique named symbol (possibly with a suffix), which will not collide with any existing symbols. Note these symbols may still collide if `SymbolTable::Register()` is called with the same name. All Transforms that currently use `SymbolTable::Register()` will be fixed in another change.
* The CloneContext has been updated to use `SymbolTable::New()` instead of `Register()`. This means that any symbols defined before a clone will not collide.
* `CloneContext::CloneSymbols()` has been added which allows a transform to pre-clone all the symbols from the source program. This can be used to avoid the authored identifiers being suffixed with a number, in the case a transform calls New() before the symbol is cloned.
* `Symbol::to_str()` has been changed to return `$<id>` instead of `tint_symbol_N`. This is to avoid any confusion between the actual name and the symbol ID.

When finding the true-head, false-head, and potentially the
premerge-head blocks of an if-selection, there was an overly
aggressive check for the true-branch or false-branch landing
on a merge block interior to the if-selection. The check was
determining if the merge block actually corresponded to the selection
header in question. If not, then it was throwing an error.
The bug was that this check must be performed only if the
target in question is actually inside the selection body.
There are cases where the target could represent a structured
exit, e.g. to an enclosing loop's merge or continue, or
an enclosing switch construct's merge.
There is still a latent bug: if either the true branch
or false branch represent such a kLoopBreak, kLoopContinue, or
kSwitchBreak edge, then those are not properly generated.
That will be fixed in a followup CL.

We define the canonical type as a type stripped of all aliases. For
example, Canonical(alias<alias<vec3<alias<f32>>>>) is vec3<f32>. This
change adds Resolver::Canonical(Type*) which caches and returns the
resulting canonical type. We use this throughout the Resolver instead of
UnwrapAliasIfNeeded(), and we store the result in semantic::Variable,
returned from it's Type() member function.
Also:
* Wrote unit tests for Resolver::Canonical()
* Added semantic::Variable::DeclaredType() as a convenience to
retrieve the AST variable's type.
* Updated post-resolve code (transforms) to make use of Type and
DeclaredType appropriately, removing unnecessary calls to
UnwrapAliasIfNeeded.
* Added IntrinsicTableTest.MatchWithNestedAliasUnwrapping to ensure we
don't need to pass canonical parameter types for instrinsic table
lookups.
* ProgramBuilder: added vecN and matMxN overloads that take a Type* arg
to create them with alias types.

In anticipation of adding support for type inference, no longer use
ast::Variable::type() everywhere, as it will eventually return nullptr
for type-inferred variables. Instead, the Resolver now stores the final
resolved type into the semantic::Variable, and nearly all code now makes
use of that.
ast::Variable::type() has been renamed to ast::Variable::declared_type()
to help make its usage clear, and to distinguish it from
semantic::Variable::Type().
Fixed tests that failed after this change because variables were missing
VariableDeclStatements, so there was no path to the variables during
resolving, and thus no semantic info generated for them.

This will be used to validate layout rules, as well as preventing
illegal types from being used in a uniform / storage buffer.
Also: Cleanup logic around VariableDeclStatement
This was spread across 3 places, entirely unnecessarily.

Remove /W3 from default flags, and disable a couple of warnings:
C4127: conditional expression is constant
C4458: declaration of 'identifier' hides class member
These match our warning settings of Clang/GCC more closely.
Also fix some valid warnings in some tests.

Use it for entry point IO sanitizing transforms to fix cases where structures were being inserted before type aliases that they reference.
Also fixes up some ordering issues with the FirstIndexOffset

This change validates that the operand types and result type of every
binary operation is valid.
* Added two unit tests which test all valid and invalid param combos. I
also removed the old tests, many of which failed once I added this
validation, and the rest are obviated by the new tests.
* Fixed VertexPulling transform, as well as many tests, that were using
invalid operand types for binary operations.

Added enforcement for vector constructor type rules according to the
table in https://gpuweb.github.io/gpuweb/wgsl.html#type-constructor-expr.
This surfaced a number of existing tests that violated some of these
rules or had a type-declaration related bug, so this CL fixes those as
well (these tests either passed the incorrect number of arguments to a
vector constructor or relied on implicit conversions between numeric
types).
