Breaks `--trace` into two flags:
- `--parser_debug`, which sets the parser debug level (which I haven't dug into piping with `--trace`, but seemed likely to be troublesome)
- `--trace_file`, which now the type checker and interpreter will use for trace information (note compile errors should use a different channel)
Most of the file edits are just mechanical testdata flag updates: `sed -i 's/--trace/--parser_debug --trace_file=-/' testdata/**/*.carbon`
To explain the output paths:
- parse/compile errors: stderr
- print() calls: stdout
- parser tracing: `--parser_debug` option, stdout (formerly stdout if `--trace`)
- type check/compile tracing: `--trace_file=<file>`, giving `-` uses stdout (formerly stdout if `--trace`)
- return code of executed Carbon code: `--trace_file` if set, stdout if not (formerly stdout always)

Also add a failing test case that tests applying the address-of operator
to an rvalue.
This enables us to stop using `Env` in the typechecker. As a byproduct, this commit also restructures the interpreter to handle run-time global initialization as part of ordinary execution, using the Action stack.
This required changing BindingPattern::name() to return `"_"` instead of nullopt when representing a `"_"` binding.
Semi-related drive-by fixes:
- Update BindingPlaceholderValue to expose a NamedEntity instead of a string name, and stop exposing its type.
- Drop the unused SourceLocation parameter of ValueEqual
As a byproduct, replace NamedEntity with a type-erasing wrapper NamedEntityView, eliminate virtual inheritance from the AST, and eliminate interfaces from gen_rtti.
Also explicitly model the types of expressions whose values are class or choice types, and make those be the static_type of the type declaration. This ensures that the static_type of a NamedEntity consistently corresponds to the static type of an IdentifierExpression using that name.
This doesn't actually use the results of name resolution, but it does verify that they are present.
Also ensures that name resolution and type checking are applied to deduced function parameters and the implicit call to `Main()`.

- Rename `PointerValue` to `LValue` to reflect how it's actually used. We can introduce a `PointerValue` type when we add support for actual pointer values.
- Remove support for pattern assignment. It's unclear if Carbon will support this, and even if we do, it raises questions that should first be addressed in a language proposal, like "is the left-hand side of `(x, y) = (1, 2)` an lvalue, or a pattern, or both, or something else entirely?"
This enables us to stop treating the return type as a Pattern (which is really isn't), treat return types more consistently with other static types in the typechecker, and drop ReturnTypeContext.
Additional changes:
- Merge TypeCheckFunDef with TypeOfFunDef.
- Handle implicit conversions in `return` statements.
- Require function type literals to have an explicit `->`.
- Move consistency check for omitted returns from TypeChecker to ResolveControlFlow.
