This fixes some basic issues with the profile test cases with autofdo.
- Disable checking for value transformations that autofdo does not
support.
- Disable checking for fixed hit counts which autofdo does not support
- Enable dumping of afdo log file and check right log file.
- Increase run time of test cases to 1M iterations because autofdo needs
a few samples to make sense of a program. The test case don't run
noticeable slower with that.
There are still failures unfortunately, especially the indirect call
transformations do not trigger because autofdo thinks they are not hot.
This can be addressed later.
Add dg-final-scan-autofdo and dg-final-scan-not-autofdo
Autofdo outputs to different dump files and doesn't support some
transformation that normal profiling. Add dg-final-scan-autofdo
and dg-final-scan-not-autofdo statements to the test suite

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.
