pr20122.c.133t.vect dump

Sorry for the long delay.  Dump attached.

I happened to do the reghunt on i386-pc-solaris2.10.  Nothing special was
required
when configuring, just --target sparc-sun-solaris2.10.

Just in case, here's the full list:

configure --with-gmp=/vol/gcc --with-mpfr=/vol/gcc --with-mpc=/vol/gcc
--without-ppl --without-cloog --enable-languages=c,c++
--enable-checking=release --disable-libgomp --disable-libquadmath
--disable-libssp --disable-libatomic --disable-libitm --disable-libcilkrts
--disable-libcc1 --disable-bootstrap --disable-multilib --target
sparc-sun-solaris2.10

I've then compiled the testcase like this:

cc1 -fpreprocessed pr20122.i -quiet -mcpu=ultrasparc -mvis -O2 -ftree-vectorize
-fvect-cost-model=unlimited -fno-common -fdump-tree-vect-details -o pr20122.s
