 		cef93fba5e Feature call destructor for tuples and bug fixes for the destructor process (#2255) 
This PR includes the following changes:
*  Added destruction process for tuples
*  Fix: In the current version only the last member of a object can be destroyed
*  Fix: In the current version, the destructor of the object is called after each method call 

I hope it is useful

Richard Smith 8f0f69b65f Remove RuntimeError / CompilationError. (#2258) 
Instead, work out the prefix for an error based on whether it was produced during parsing, semantic analysis, or when running the program.

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

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.
