  Revert "[SimplifyCFG] FoldBranchToCommonDest: lift use-restriction on bonus instructions"

Many bots are unhappy, at the very least missed a few codegen tests,
and possibly this has a logic hole inducing a miscompile
(will be really awesome to have ready reproducer..)

Need to investigate.

This reverts commit 2245fb8aaa1c1f85f53f7b19a1ee3ac69b1a1dfe.
