Created attachment 30016
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30016
amended patch

Using an i686-px-linux-gnu X hppa64-hp-hpux11.11 cross compiler, I've
verified that the previous patch fixes the gcc.c-torture/compile/991202-1.c
and gcc.dg/pr52132.c failures.  The gcc.dg/pr41345.c compare-debug failure
happens independent of my code in convert_mult_to_fma.
I can't run the gcc.dg/torture/vec-cvt-1.c tests on my cross for lack of header
files.

The preprocessed testcase from the first attachment fails needs a different
sanity check in convert_mult_to_fma, which I have added in this amended patch.
