[PATCH] Remove raw string and raw byte string references from ast and hir

[Mark Wielaard <mark@klomp.org>]

Raw strings and raw byte strings are simply different ways to
create string and byte string literals. Only the lexer cares
how those literals are constructed and which escapes are used
to construct them. The parser and hir simply see strings or
byte strings.
