[arm] Replace command-line option .def files with single definition file

The files arm-cores.def, arm-fpus.def and arm-arches.def are parsed and
used in several places and the format is slightly awkward to maintain
as they must be parsable in C and by certain scripts.  Furthermore,
changes to the content that affects every entry is particularly awkward for
dealing with merges.

This patch replaces all three files with a single file that specifies all
the command-line related definitions in a new format that allows for better
checking for consistency as well as (hopefully) easier to merge changes.

The awk script used to parse it is relatively complicated, but should be
pretty portable.  It works by parsing in all the data and then operating
one of a number of possible sub-commands to generate the desired output.

The new method picked up one error.  The CPU descriptions referred to an
architecture ARMv5tej which was not supported by -march.  This has been
fixed by adding the relevant entry to the architecture list.

Fix issues with unrepresentable column numbers (PR c++/77949)

PR c++/77949 identifies an ICE when the C++ frontend attempts to emit a
fix-it hint inserting a missing semicolon at column 4097 of a source file.

This column value exceeds LINE_MAP_MAX_COLUMN_NUMBER and hence isn't
representable using a location_t.

Attempting to do so leads to these problems, which this patch fixes:

(a) when encountering a column number > LINE_MAP_MAX_COLUMN_NUMBER we
create a new linemap with m_column_and_range_bits == 0, but
linemap_position_for_column doesn't check for this, and hence can emit
a bogus location_t value that's calculated relative to the previous
linemap start, but which will be decoded relative to the new linemap,
leading to very large incorrect line values.

(b) when encountering a column number that can't be represented, and
for which the linemap was pre-existing, the code would hit this assertion:
  if (linemap_assert_fails (column < (1u << map->m_column_and_range_bits)))
around a bail-out condition.  The patch replaces this assertion with a
simple conditional, to stop the ICE when this occurs, and fixes the
bit count (effective column bits, vs column+range bits)

(c) the C++ frontend wasn't checking for failure of
linemap_position_for_loc_and_offset when considering emitting the fix-it
hint.  The patch adds a conditional, so that no fix-it hint is emitted
if the location is bogus.

compiler, runtime: drop size arguments to hash/equal functions

    Drop the size arguments for the hash/equal functions stored in type
    descriptors.  Types know what size they are.  To make this work,
    generate hash/equal functions for types that can use an identity
    comparison but are not a standard size and alignment.

    Drop the multiplications by 33 in the generated hash code and the
    reflect package hash code.  They are not necessary since we started
    passing a seed value around, as the seed includes the hash of the
    earlier values.

    Copy the algorithms for standard types from the Go 1.7 runtime,
    replacing the C functions.
