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.

* Module-scope declarations can no longer alias a builtin name. [tint:1318](https://crbug.com/tint/1318)
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.
