fix-it hints: insert_before vs insert_after
The API for adding "insert text" fix-it hints was unclear
about exactly where the text should be inserted relative
to the given insertion point.
This patch clarifies things by renaming the pertinent methods from
richloc.add_fixit_insert
to
richloc.add_fixit_insert_before
and adding:
richloc.add_fixit_insert_after
The latter allows us to consolidate some failure-handling into
class rich_location, rather than having to have every such diagnostic
check for it.
The patch also adds a description of how fix-it hints work to the
comment for class rich_location within libcpp/include/line-map.h.
