Allow top level ticked string literals
This reverts f5b275a239d2554c4da0b7621211642bf3b10650 and changes the places that looked for `Lit (MachStr _))` to use `exprIsMbTickedLitString_maybe` to unwrap ticks as necessary. Also updated relevant comments. Test Plan: I added 3 new tests that previously reproduced. GHC HEAD now builds with -g Reviewers: simonpj, simonmar, bgamari, hvr, goldfire Subscribers: rwbarton, thomie, carter GHC Trac Issues: #14779 Differential Revision: https://phabricator.haskell.org/D4470
