Use of semicolons is still supported, but deprecated.

Also updates the parsing methods for structures to better match the

dfc1a2c081 Remove support for the @stride attribute 
We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.

The WGSL parser no longer has to handle attributes on types.

d0ec88ce61 Add support for override keyword and @id attribute 
This replaces the @override keyword that was previously used for
pipeline-overridable constants.

Support for pipeline-overridable constants in Dawn is hidden behind
the "disallow-unsafe-APIs" toggle, so we can make this change directly
instead of deprecating and continuing to support the old syntax.

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.

bf39c8fb19 sem: Replace SwitchCaseBlockStatement with CaseStatement 
The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.

With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.

a40e45522b intrinsics: Deprecate isNan, isInf, isFinite, isNormal 
These have all been removed from the spec as we cannot guarantee they will behave as expected on the various backends.

177e7bfa5d IntrinsicTable: remove double underscores 
'__' is reserved in C++, and the 'match__' and 'build__' functions are causing OSS-fuzz builds to fail.

Add the change in tint behavior to the OT notes.

Add end to end tests for underscores. While the GLSL and MSL compilers seem to accept leading and double underscores in identifiers, the tint build failure has highlighted we have more work to do here (crbug.com/tint/1319)
