MacOS only: VG_(get_changed_segments) callback
remove_mapping_callback: if the kernel tells us of a gap that
partially, but does not exactly, overlap a V segment, only record
directives to remove that part of the segment that actually falls
within the gap. Removing the entire V segment is incorrect and can
cause Memcheck to believe that memory not within the hole is
inaccessible, leading to floods of invalid errors. Fixes
