Relands this feature after several fixes: * Force fake uses to be emitted before musttail calls (#136867) * Added soften-float legalization for fake uses (#142714) * Treat fake uses as size-less instructions in a SystemZ assert (#144390) If further issues with fake uses are found then this may be reverted again, but all currently-known issues are resolved. This reverts commit 2dc6e98169baeb1f73036da0ea50fd828d8323d0.
