Remove explicit insertion of the AllocTokenPass, which is now handled by the PassBuilder. Emit AllocToken configuration as LLVM module flags to persist into the backend. Specifically, this also means it will now be handled by LTO backend phases; this avoids interference with other optimizations (e.g. PGHO) and enable late heap-allocation optimizations with LTO enabled.
