This adds a cc1 flag to enable constructor homing but doesn't turn on debug info if it wasn't enabled already (which is what using -debug-info-kind=constructor does). This will be used for testing, and won't be needed anymore once ctor homing is used as default / merged into =limited. Bug to enable ctor homing: https://bugs.llvm.org/show_bug.cgi?id=46537 Differential Revision: https://reviews.llvm.org/D85799
