6ff5b471ef Fix issue #72649: avoid spurious "previous iteration of loop" errors.
Only follow backwards edges during get_moved_indexes if the move path is
definitely initialized at loop entry. Otherwise, the error occurred prior to the
loop, so we ignore the backwards edges to avoid generating misleading "value
moved here, in previous iteration of loop" errors.

This patch also slightly improves the analysis of inits, including
NonPanicPathOnly initializations (which are ignored by
drop_flag_effects::for_location_inits). This is required for the definite
initialization analysis, but may also help find certain skipped reinits in rare
cases.

Patch passes all non-ignored src/test/ui testcases.
