Tweak BB analysis for dr_analyze_innermost

dr_analyze_innermost had a "struct loop *nest" parameter that acted
like a boolean.  This was added in r179161, with the idea that a
null nest selected BB-level analysis rather than loop analysis.

The handling seemed strange though.  If the DR was part of a loop,
we still tried to express the base and offset values as IVs, potentially
giving a nonzero step.  If that failed for any reason, we'd revert to
using the original base and offset, just as we would if we hadn't asked
for an IV in the first place.

It seems more natural to use the !in_loop handling whenever nest is null
and always set the step to zero.  This actually enables one more SLP
opportunity in bb-slp-pr65935.c.

I checked out r179161 and tried the patch there.  The test case added
in that revision still passes, so I don't think there was any particular
need to check simple_iv.

Reorganise machmode.h headers

This patch splits the auto-generated inline functions out of
insn-modes.h and puts them in a new header file, insn-modes-inline.h.
It also makes coretypes.h include these files directly, rather than
indirectly via machmode.h.  This in turn allows insn-modes-inline.h
and machmode.h to come later in the include list, after wide-int.h.
This is useful for later patches.

insn-modes.h itself still needs to come first, since it provides
configuration information like MAX_BITSIZE_MODE_ANY_INT, which is
used to control the size of a wide_int.

The patch also makes the generator files include machmode.h
via coretypes.h.  Previously they did it by more indirect means.

Finally, the patch makes wide-int-print.h available via coretypes.h
too.  There didn't seem to be any reason to force only the print
routines to be included directly, and it would be painful to extend
that approach to the SVE patches.

Make tree-ssa-strlen.c handle partial unterminated strings

tree-ssa-strlen.c looks for cases in which a string is built up using
operations like:

    memcpy (a, "foo", 4);
    memcpy (a + 3, "bar", 4);
    int x = strlen (a);

As a side-effect, it optimises the non-final memcpys so that they don't
include the nul terminator.

However, after removing some "& ~0x1"s from tree-ssa-dse.c, the DSE pass
does this optimisation itself (because it can tell that later memcpys
overwrite the terminators).  The strlen pass wasn't able to handle these
pre-optimised calls in the same way as the unoptimised ones.

This patch adds support for tracking unterminated strings.

PR 80769: Incorrect strlen optimisation

In this testcase, we (correctly) record after:

  strcpy (p1, "abcde");
  char *p2 = strchr (p1, '\0');
  strcpy (p2, q);

that the length of p1 and p2 can be calculated by converting the
second strcpy to:

  tmp = stpcpy (p2, q)

and then doing tmp - p1 for p1 and tmp - p2 for p2.  This is delayed
until we know whether we actually need it.  Then:

  char *p3 = strchr (p2, '\0');

forces us to calculate the length of p2 in this way.  At this point
we had three related strinfos:

  p1: delayed length, calculated from tmp = stpcpy (p2, q)
  p2: known length, tmp - p2
  p3: known length, 0

After:

  memcpy (p3, "x", 2);

we use adjust_related_strinfos to add 1 to each length.  However,
that didn't do anything for delayed lengths because:

  else if (si->stmt != NULL)
    /* Delayed length computation is unaffected.  */
    ;

So after the memcpy we had:

  p1: delayed length, calculated from tmp = stpcpy (p2, q)
  p2: known length, tmp - p2 + 1
  p3: known length, 1

where the length of p1 was no longer correct.

PR81136: ICE from inconsistent DR_MISALIGNMENTs

The test case triggered this assert in vect_update_misalignment_for_peel:

      gcc_assert (DR_MISALIGNMENT (dr) / dr_size ==
                  DR_MISALIGNMENT (dr_peel) / dr_peel_size);

The problem was that:

- one memory reference guaranteed a high base alignment, when considering
  that reference in isolation.  This meant that we could calculate the
  vector misalignment for its DR at compile time.

- the other memory reference only guaranteed a low base alignment,
  when considering that reference in isolation.  We therefore couldn't
  calculate the vector misalignment for its DR at compile time.

- when looking at the values of the two addresses as a pair (rather
  than the memory references), it was obvious that they had the same
  misalignment, whatever that misalignment happened to be.

This is working as designed, so the patch restricts the assert to cases
in which both addresses have a compile-time misalignment.

In the test case this looks like a missed opportunity.  Both references
are unconditional, so it should be possible to use the highest of the
available base alignment guarantees when analyzing each reference.
A later patch does this, but the problem would still remain for
conditional references.

[rtlanal] Do a better job of costing parallel sets containing flag-setting operations.

Many parallel set insns are of the form of a single set that also sets
the condition code flags.  In this case the cost of such an insn is
normally the cost of the part that doesn't set the flags, since
updating the condition flags is simply a side effect.

At present all such insns are treated as having unknown cost (ie 0)
and combine assumes that such insns are infinitely more expensive than
any other insn sequence with a non-zero cost.

This patch addresses this problem by allowing insn_rtx_cost to ignore
the condition setting part of a PARALLEL iff there is exactly one
comparison set and one non-comparison set.  If the only set operation
is a comparison we still use that as the basis of the insn cost.

* rtlanal.c (insn_rtx_cost): If a parallel contains exactly one
comparison set and one other set, use the cost of the non-comparison
set.
