* Simplify thread0.cpp and xthrow.cpp. I verified with `#error` that these files are always compiled with `_HAS_EXCEPTIONS=1`. thread0.cpp Include only necessary headers. Move the lookup tables within `_STD_BEGIN` to avoid repeated `_STD` qualification. They're `static`, so this doesn't affect bincompat. Add trailing commas for readability. Make `codes` a table of `errc` so we don't need to cast each value. Mark `_Throw_Cpp_error` as `[[noreturn]]`, matching its declaration in the header. (No bincompat effect.) Use `_THROW` for consistency. (Even though exceptions are enabled, we conventionally use this in `src`.) `system_error` is a type, so we don't need to `_STD` qualify it. `static_cast<int>` the `errc`, once. xthrow.cpp Coalesce headers. Coalesce `std` regions. Remove unnecessary comments. Mark value parameters as const. * Add constexpr.
