[CodeLayout] Do not rebuild chains with -apply-ext-tsp-for-size (#115934)
https://github.com/llvm/llvm-project/pull/109711 disables
`buildCFGChains()` when `-apply-ext-tsp-for-size` is used to improve
codesize. Tail merging can change the layout and normally requires
`buildCFGChains()` to be called again, but we want to prevent this when
optimizing for codesize. We saw slight size improvement on large
binaries with this change. If `-apply-ext-tsp-for-size` is not used,
this should be a NFC.
