Rename literal constructors
In a previous patch we replaced some built-in literal constructors
(MachInt, MachWord, etc.) with a single LitNumber constructor.
In this patch we replace the `Mach` prefix of the remaining constructors
with `Lit` for consistency (e.g., LitChar, LitLabel, etc.).
Sadly the name `LitString` was already taken for a kind of FastString
and it would become misleading to have both `LitStr` (literal
constructor renamed after `MachStr`) and `LitString` (FastString
variant). Hence this patch renames the FastString variant `PtrString`
(which is more accurate) and the literal string constructor now uses the
least surprising `LitString` name.
Both `Literal` and `LitString/PtrString` have recently seen breaking
changes so doing this kind of renaming now shouldn't harm much.
