[PR100066] Check paradoxical subreg when splitting hard reg live range

When splitting live range of a hard reg, LRA actually split multi-register
containing the hard reg.  So we need to check the biggest used mode of the
hard reg on
paradoxical subregister when the natural and the biggest
mode are ordered.

gcc/ChangeLog:

PR rtl-optimization/100066
* lra-constraints.c (split_reg): Check paradoxical_subreg_p for
ordered modes when choosing splitting mode for hard reg.

gcc/testsuite/ChangeLog:

PR rtl-optimization/100066
* gcc.target/i386/pr100066.c: New.

Thank you for reporting this.  I've reproduced this bug.  It seems something
wrong  with hard reg live range splitting.  This code is complicated so I can
not say when it will be fixed but I'll do my best to fix this as soon as
possible.
