Now that path::operator/=(basic_string_view<value_type>) works directly
from the string argument, instead of constructing a temporary path from
the string, it's potentially more efficient to do 'path(x) /= s' instead
of 'x / s'. This changes the only relevant place in the library.

	string to lvalue to avoid creating temporary path.

2. hash table traverse of index_string

find_slot_with_hash has

 if (insert == INSERT && m_size * 3 <= m_n_elements * 4)
    expand ();

which may expand hash table even if no insertion is neeed and change hash
table traverse order.  When output_macinfo_op is called, all index strings
have been added to hash table by save_macinfo_strings and we shouldn't
expand index string hash table.  Otherwise find_slot_with_hash will expand
hash table when hash table has the right size and hash table traverse of

This patch adds a pass that versions loops with variable index strides
for the case in which the stride is 1.  E.g.:

    for (int i = 0; i < n; ++i)
      x[i * stride] = ...;

becomes:

    if (stepx == 1)
      for (int i = 0; i < n; ++i)
        x[i] = ...;
    else
      for (int i = 0; i < n; ++i)
        x[i * stride] = ...;

This is useful for both vector code and scalar code, and in some cases
can enable further optimisations like loop interchange or pattern
recognition.

The pass gives a 7.6% improvement on Cortex-A72 for 554.roms_r at -O3
and a 2.4% improvement for 465.tonto.  I haven't found any SPEC tests
that regress.

Sizewise, there's a 10% increase in .text for both 554.roms_r and
465.tonto.  That's obviously a lot, but in tonto's case it's because
the whole program is written using assumed-shape arrays and pointers,
so a large number of functions really do benefit from versioning.
roms likewise makes heavy use of assumed-shape arrays, and that
improvement in performance IMO justifies the code growth.

The next biggest .text increase is 4.5% for 548.exchange2_r.  I did see
a small (0.4%) speed improvement there, but although both 3-iteration runs
produced stable results, that might still be noise.  There was a slightly
larger (non-noise) improvement for a 256-bit SVE model.

481.wrf and 521.wrf_r .text grew by 2.8% and 2.5% respectively, but
without any noticeable improvement in performance.  No other test grew
by more than 2%.

Although the main SPEC beneficiaries are all Fortran tests, the
benchmarks we use for SVE also include some C and C++ tests that
benefit.

Using -frepack-arrays gives the same benefits in many Fortran cases.
The problem is that using that option inappropriately can force a full
array copy for arguments that the function only reads once, and so it
isn't really something we can turn on by default.  The new pass is
supposed to give most of the benefits of -frepack-arrays without
the risk of unnecessary repacking.

The patch therefore enables the pass by default at -O3.
