The field is also renamed from ident to name. In most cases,
we don't actually need the Span. A new ident method is added
to VariantDef and FieldDef, which constructs the full Ident
using tcx.def_ident_span(). This method is used in the cases
where we actually need an Ident.
This makes incremental compilation properly track changes
to the Span, without all of the invalidations caused by storing
a Span directly via an Ident.
