* Fixed a couple simple crashes surfaced by running a structured fuzzer on executable_semantics parse/type-check/execute logic.
* var a: b: auto; -> var a: auto;
In the process, switch to an unambiguous grammar, using the
precedence-climbing method for operator precedence (suitably modified to
handle a partial precedence order) rather than Bison %precedence /
%prec.
Line 91 has:
```
source_loc_(type_expression->source_loc()) {}
```
Which requires the Expression definition. This probably compiles accidentally due to #include ordering, but I ran into a case that needs correct #includes.
This switches to generating per-file targets such as `//executable_semantics/testdata:tuple/equality_false.carbon.test`, instead of one test covering all files. Essentially this relies on bazel instead of lit to handle test parallelization.

* Implement changes suggested by @geoffromer
Also add a failing test case that tests applying the address-of operator
to an rvalue.
I think lit_test accrued a bit of cruft as I switched approaches... I still may go further, but this is particularly fixing a bug where `FileCheck` (instead of `%{FileCheck}`) should've failed in tests.
* Initial implementation of block string literals following lexical_conventions/string_literals.md.
Enabled yyinput() in flex to implement parsing.
Added ParseBlockStringLiteral() helper to handler further transformations such as indenting.
Modified formar_grammar to support single-quoted strings to prevent a failure on lexer.lpp.
* Fixed _find_string_end quote parameter type int -> str.
* Update executable_semantics/syntax/BUILD

* Addressed code review comments - split table-drived test into individual tests, renamed constants to match style guide.
* Addressed code review comments -- using EXPECT_THAT_EXPECTED() in tests, lexer comments and code cleanup.

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()`.
