    • input.c: add lexing selftests and a test matrix for line_table states · 741d3be5 
      This patch adds explicit testing of lexing a source file,
generalizing this (and the test of ordinary line maps) over
a 2-dimensional test matrix covering:

  (1) line_table->default_range_bits: some frontends use a non-zero value
  and others use zero

  (2) the fallback modes within line-map.c: there are various threshold
  values for source_location/location_t beyond line-map.c changes
  behavior (disabling of the range-packing optimization, disabling
  of column-tracking).  We exercise these by starting the line_table
  at interesting values at or near these thresholds.

This helps ensures that location data works in all of these states,
and that (I hope) we don't have lingering bugs relating to the
transition between line_table states.

	* input.c: Include cpplib.h.

	(selftest::assert_loceq): Only verify LOCATION_COLUMN for
	locations that are known to have column data.
	(selftest::line_table_case): New struct.
