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.

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.

The readers must not produce invalid ASTs.
If readers cannot produce a valid AST, then they should error instead.
If a reader does produce an invalid AST, this change catches this bad behavior early, significantly helping identify the root of the broken logic.
IsValid() made a bit more sense in the days where the AST was mutable, and was constructed by calling setters on the nodes to build up the tree.
In order to detect bad ASTs, IsValid() would have to perform an entire AST traversal and give a yes / no answer for the entire tree. Not only was this slow, an answer of 'no' didn't tell you *where* the AST was invalid, resulting in a lot of manual debugging.
Now that the AST is fully immutable, all child nodes need to be built before their parents. The AST node constructors now become a perfect place to perform pointer sanity checking.
The argument for attempting to catch and handle invalid ASTs is not a compelling one.
Invalid ASTs are invalid compiler behavior, not something that should ever happen with a correctly functioning compiler.
If this were to happen in production, the user would be utterly clueless to _why_ the program is invalid, or _how_ to fix it.
Attempting to handle invalid ASTs is just masking a much larger problem.
Let's just let the fuzzers do their job to catch any of these cases early.

In this situation the parser may try to reparse the same token, forever.
By calling sync_to() we either find the end of the block, and forward progress can be made, or synchronized_ is set to false, and the parser can error out cleanly.

Pull the mutable semantic field from ast::Identifier and into a new semantic nodes.
Have the TypeDeterminer create these new semantic nodes.
Note: This change also fixes the node that holds the semantic information for a call.
Previously this was on the identifier, and this is now correctly on the CallExpression.
The identifier of the CallExpression should resolve to the target function, not the return type.
Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.
