Integrate spans to existing types. gcc/rust/ChangeLog: * util/rust-token-converter.cc (convert): Update call to constructors with location information. (handle_suffix): Convert token locus to a Span and use it in the literal. libgrust/ChangeLog: * libproc_macro/Makefile.am: Add span.cc * libproc_macro/Makefile.in: Regenerate. * libproc_macro/span.cc: New file. * libproc_macro/span.h: New file. * libproc_macro/group.cc (Group::make_group): Add span argument. * libproc_macro/group.h (GROUP_H): Add include directive for spans. * libproc_macro/ident.cc (Ident__new): Add span argument. (Ident__new_raw): Likewise. (Ident::make_ident): Likewise. * libproc_macro/ident.h (Ident__new): Likewise. (Ident__new_raw): Likewise. * libproc_macro/literal.cc (Literal::clone): Clone the span. (Literal::make_literal): Add span argument. (Literal::make_u8): Likewise. (Literal::make_u16): Likewise. (Literal::make_u32): Likewise. (Literal::make_u64): Likewise. (Literal::make_i8): Likewise.
