    sched1: Fix -fcompare-debug issue in schedule_region [PR105586]

This failure is on a big endian system and it seems to work fine on LE.  The
new test case does not guard against unsupported __int128.

Assigning to Surya.

It looks like the test case just needs a...

/* { dg-require-effective-target lp64 } */

...line to disable it on -m32 compiles, since __int128 isn't supported there.

/* { dg-require-effective-target int128 } */
might be better if it is just __int128 that is causing the issue.

    testsuite: Fix failure in test pr105586.c [PR107171]

    The test pr105586.c fails on a big endian system when run in 32bit
    mode. The failure occurs as the test case does not guard against
    unsupported __int128.
