input.c: add lexing selftests and a test matrix for line_table states
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.

FT32: apply unbias to references to RAM symbols.
The FT32 binutils use a bias to distinguish between RAM and flash
addresses.
This fix adds an ASM_OUTPUT_SYMBOL_REF() that unbiases references to
RAM symbols.
Only references to RAM objects have the bias applied. Flash objects
(that is, objects in ADDR SPACE 1) are not biased, so for these no bias
should be applied. Likewise references in the gdb section need to use
the biased address, so references in debug sections are not unbiased.
