[Committed] Add testcase for PR target/37381 (ICE in ia64_speculate_insn)

[Alexander Monakov <amonakov at ispras dot ru>]

Hello.

Problem described in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37381 was due
to a discrepancy in handling of speculative attributes in scheduler and ia64
back-end, and appeared with selective scheduler merge.  Since ia64 changes
from sel-sched branch are committed, the problem is resolved, but the
testcase from the PR was not checked in.  Thanks to H.J. Lu for reminding to do
so in the audit trail.

Committed to trunk.
