  -----------
  [lld] Fix -ObjC load behavior with LTO for section names with whitespace (#146654)

This is a fix additional to #92162

In some cases, section names contain a whitespace between the segment
name and the actual section name (e.g. `__TEXT, __swift5_proto`). It is
confirmed by source code of the Swift compiler

This fix allows LTO to work correctly with the `-ObjC` flag in that rare
case when only a section with a whitespace in the name is present in the
linked bitcode module, but there are no sections containing
`__TEXT,__swift`
