Jon Ross-Perkins 39155d34ae Remove experimental continuation support (#2776) 
Removes `__continuation`, `__await`, and `__run`.

In part here, the discussion was that while the feature had been useful for validating the early explorer design, it's no longer needed for that role as the explorer is now quite robust. Continuations have been experimental and, at this point, don't have an owner pushing to a proposal.

The triggering factor is that, as we push to address fuzzer issues, I ran into a crash bug in this code; basically, `fn Main() -> i32 { __await; return 0; }`. When I mentioned this, the reaction seemed to trend towards removal of the feature.

josh11bandGeoff Romer 46503c0a9d Explorer and toolchain changes to implement #2483 (#2707) 
This PR is making two main changes to the Explorer and Toolchain:
- Replace the `is` keyword in `where SomeType is SomeInterface` with `impls`, so it is `where SomeType impls SomeInterface`
- Rewrite uses of the "impls" to something else to avoid, frequently "`impl` declarations" or "implementations", to avoid confusion with the `impls` keyword.

Richard Smith 4fa71e32f5 Add support for most kinds of declarations to be declared and used as namespace members (#2575) 
Support for global variables is still missing; they're a bit more tricky because they use a pattern to introduce their name.

Prior to this change, explorer heavily relied on name comparisons to determine whether two declarations declare the same entity. Some of those instances are fixed in this PR, but more remain to be fixed, and some TODOs are added for some harder-to-fix instances.

Richard Smith 59ae6e31b6 Rename PrimitiveOperatorExpression to OperatorExpression. (#1530) 
This isn't modeling only primitive operators any more: it also models operators
that are rewritten as calls to an interface function.

Darshal Shetty e4a2d0f047 Addr Keyword Implementation (#1255) 
* Implement addr keyword

* Add files that were deleted during merge

Some files got deleted during merging trunk because of the executable
semantics rename.

* Implement changes from code review.

Major changes:
- Rename AddrBindingPattern to AddrPattern
- Fix AddrPattern related changes in fuzzing

* Update documentation for GetField

* Fix AddPattern according to @zygoloid's suggestions

* Apply @zygoloid's changes to method comment

* Add a multi-component field example

* Incorporate AST changes to fuzzer corpus

* Refactor the deduced_param_list grammar rule

pk19604014 45b18098ed Add continuation name to name resolution after processing continuation body (#1264) 
Fixes #1263

This makes the continuation behave similar to this C++ lambda construct - auto f = []() { f(); }; which doesn't compile.

pk19604014 88be617360 Changed ExpectReturnOnAllPaths() to treat continuation, run and await as missing returns (#1258)

pk19604014 589930b703 Fix for a crash caused by choice alternative name being the same as choice name (#1243) 
Fixes #1248

Changed resolve names logic to add choice name to name resolution after choice's alternatives are added.
