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.

rs6000: Make the ctr* patterns allow ints in vector regs (PR71763)

Similar to PR70098, which is about integers in floating point registers,
we can have the completely analogous problem with vector registers as well
now that we allow integers in vector registers.  So, this patch solves it
in the same way.  This only works for targets with direct move.

To recap: register allocation can decide to put an integer mode value in
a floating point or vector register.  If that register is used in a bd*z
instruction, which is a jump instruction, reload can not do an output
reload on it (it does not do output reloads on any jump insns), so the
float or vector register will remain, and we have to allow it here or
recog will ICE.  Later on we will split this to valid instructions,
including a move from that fp/vec register to an int register; it is this
move that will still fail (PR70098) if we do not have direct move enabled.
