[debuginfo] Make debuginfo type names for slices and str consistent.
Before this PR, the compiler would emit the debuginfo name `slice$<T>`
for all kinds of slices, regardless of whether they are behind a
reference or not and regardless of the kind of reference. As a
consequence, the types `Foo<&[T]>`, `Foo<[T]>`, and `Foo<&mut [T]>`
would end up with the same type name `Foo<slice$<T> >` in debuginfo,
making it impossible to disambiguate between them by name. Similarly,
`&str` would get the name `str` in debuginfo, so the debuginfo name for
`Foo<str>` and `Foo<&str>` would be the same. In contrast,
`*const [bool]` and `*mut [bool]` would be `ptr_const$<slice$<bool> >`
and `ptr_mut$<slice$<bool> >`, i.e. the encoding does not lose
information about the type.
This PR removes all special handling for slices and `str`. The types
`&[bool]`, `&mut [bool]`, and `&str` thus get the names
`ref$<slice2$<bool> >`, `ref_mut$<slice2$<bool> >`, and
`ref$<str$>` respectively -- as one would expect.
