Using the flag `-split_layout` in llvm-profdata merge, the output profile can write profiles with and without inlined function into two different extbinary sections (and their FuncOffsetTable too). The section without inlined functions are marked with `SecFlagFlat` and is skipped by ThinLTO because it provides no useful info. The split layout feature was already implemented in SampleProfWriter but previously there is no way to use it from llvm-profdata.
