Rollup merge of rust-lang#64052 - ranweiler:debuginfo-boxed-struct-64…

…050, r=alexcrichton

Rename test locals to work around LLDB bug

LLDB's expression parser can't unambiguously resolve local variables in
some cases, as described in rust-lang#47938. Work around this by using names that
don't shadow direct submodules of `core`.

Closes rust-lang#64050.
