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.

gcc/c-family/ChangeLog:
* c-common.c (warn_logical_not_parentheses): Replace
rich_location::add_fixit_insert calls with add_fixit_insert_before
and add_fixit_insert_after, eliminating the "next_loc" calculation.

gcc/c/ChangeLog:
* c-parser.c (c_parser_declaration_or_fndef): Update for renaming
of add_fixit_insert to add_fixit_insert_before.
