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.

josh11bandJon Meow 0a93289706 Add support for Self and impl as (#1194) 
- Makes `Self` a keyword
- Inside `class Foo { `... `}`, `Self` means `Foo`
- Inside `class Foo(T:! Type, U:! Type) {` ...` }`, `Self` means `Foo(T, U)`
- `impl as Bar` means `impl Self as Bar`
- Inside `external impl Foo as Bar {`...`}`, not in a scope already defining `Self`, `Self` means `Foo`

Implemented by introducing a new kind of declaration, a `SelfDeclaration`, that is automatically added to class and impl declarations.
