Richard Smith 17ee3ed9b7 Track a resolved Member on each member access expression. (#1333)
Type checking now stores information on a member access identifying the member that was accessed, not only its name. This parallels what we do for other similar constructs whose meaning is resolved by name lookup or type-checking, and will allow us to avoid redoing lookups in some cases during interpretation.

Richard Smith 2fef76e58c Basic support for .Self within :! bindings and where expressions. (#1311)
`.Self` is modeled as a new kind of expression, `DotSelfExpression`. Name resolution associates each occurrence of a `DotSelfExpression` with a generic binding, much like for an `IdentifierExpression`.

Both `:!` bindings and `where` expressions bring `.Self` into scope. The tentative intent is that if there are multiple `.Self`s in scope and they refer to different bindings, the result of using a `.Self` expression is an ambiguity error, but that is not implemented in this patch. Instead, like for `IdentifierExpression`s, we find the innermost enclosing definition of `.Self`.

`.Foo` expressions are rewritten to `.Self.Foo`, but this isn't enough to make them do anything useful, because associated constants aren't supported in general yet.

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

Richard Smith 4cf7ed4f12 Rename some classes to match the design better (#1287)
* `FieldAccessExpression` -> `SimpleMemberAccessExpression`
    * Member `aggregate` -> `object`
    * Member `field` -> `member`
* `CompoundFieldAccessExpression` -> `CompoundMemberAccessExpression`
* `GetField` -> `GetMember`

As discussed in #1233.

Jon Meow 20728dbd3a CARBON_ header guards (#1261)
This modifies scripts/check_header_guards.py to add the CARBON_ prefix; everything else is pre-commit.

Richard SmithandJon Meow c29f56e667 Initial support for generic parameters that are introduced in a function parameter list (#1247)
In order for this to work, we need to always use the argument deduction code path for function calls, instead of only using it when there is a `[...]` list, which means that argument deduction now needs to support implicit conversion.

Jon Meow af694b97cb Prefix most macro names with CARBON_ (#1232)
I'm doing this to avoid macro name conflicts, following https://google.github.io/styleguide/cppguide.html#Preprocessor_Macros: "If you do export a macro from a header, it must have a globally unique name. To achieve this, it must be named with a prefix consisting of your project's namespace name (but upper case)."

Commands run:

```
sed -i 's/\(DCHECK\|CHECK\|FATAL\|MAKE_UNIQUE_NAME\|MAKE_UNIQUE_NAME_IMPL\|RAW_EXITING_STREAM\|RETURN_IF_ERROR\|RETURN_IF_ERROR_IMPL\|ASSIGN_OR_RETURN\|ASSIGN_OR_RETURN_IMPL\|DIAGNOSTIC_KIND\|RETURN_IF_STACK_LIMITED\)(/CARBON_\1(/g' $(git ls-files *.cpp *.h *.lpp *.ypp *.def ':!third_party')
sed -i 's/#undef DIAGNOSTIC_KIND/#undef CARBON_DIAGNOSTIC_KIND/' toolchain/diagnostics/diagnostic_registry.def
```

Note this isn't *quite* everything, but it's intended to be a large pass at everything:

```
╚╡git grep '#define ' *.cpp *.h *.lpp *.ypp *.def ':!third_party' | grep -v '#define CARBON' | grep -v _H_
explorer/syntax/lexer.lpp:  #define YY_USER_ACTION                                             \
explorer/syntax/lexer.lpp:  #define SIMPLE_TOKEN(name) \
explorer/syntax/lexer.lpp:  #define ARG_TOKEN(name, arg) \
explorer/syntax/parse_and_lex_context.h:#define YY_DECL                                                         \
migrate_cpp/cpp_refactoring/var_decl.cpp:#define ABSTRACT_TYPE(Class, Base)
migrate_cpp/cpp_refactoring/var_decl.cpp:#define TYPE(Class, Base)     \
```

We may in particular want to do a pass to clean up #ifdef guards and make them be CARBON_ rooted.
