ENOPATCH.  Trying again...

Hi,

As discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68644,
the test case gcc.dg/tree-ssa/ivopts-lt-2.c does not apply to POWER
targets, as the cost model properly shows the pre-increment approach
to be preferable and results in ideal code generation.  Thus, adding
powerpc*-*-* to the list of targets to skip for this test.

Verified on powerpc64le-unknown-linux-gnu.  Is this ok for trunk?

Thanks,
Bill
