  Log Message:
  -----------
  SourceManager: Encapsulate line number mapping into SrcMgr::LineOffsetMapping

Put the guts of `ComputeLineNumbers` into `LineOffsetMapping::get` and
`LineOffsetMapping::LineOffsetMapping`.  As a drive-by, store the number
of lines directly in the bump-ptr-allocated array.
