reflect this behavior by deprecating values passed to the
--split-function option.

BOLT. Assuming your environment is setup to include the right path, execute
`llvm-bolt`:
```
-$ llvm-bolt <executable> -o <executable>.bolt -data=perf.fdata -reorder-blocks=ext-tsp -reorder-functions=hfsort -split-functions=2 -split-all-cold -split-eh -dyno-stats
+$ llvm-bolt <executable> -o <executable>.bolt -data=perf.fdata -reorder-blocks=ext-tsp -reorder-functions=hfsort -split-functions -split-all-cold -split-eh -dyno-stats
```
If you do need an updated debug info, then add `-update-debug-sections` option
