Ben Clayton ea3eee9885 resolver: Migrate validation to behavior analysis
Migrate some of the validation logic over to use the results of behavior
analysis.

The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
  example, if all branches of a if-statement or switch-statement either
  return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
  https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
  conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
  using the new RemoveUnreachableStatements transform.

Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.

Ben Clayton b05e185a36 resolver: Support shadowing
Add transform::Unshadow to renamed shadowed symbols. Required by a
number of other transforms.

Replace Resolver symbol resolution with dep-graph.

The dependency graph now performs full symbol resolution before the
regular resolver pass.
Make use of this instead of duplicating the effort.

Simplfies code, and actually performs variable shadowing consistently.

James Price 4cc4315d6c Allow array size to be a module-scope constant
Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.

The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.
