[Bug middle-end/31497] FAIL: gcc.dg/builtins-59.c on PA HP-UX

["danglin at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Regarding builtins-59.c, I believe it fails because expand_builtin_sincos()
returns NULL_RTX if the sincos insn is not available.  Possibly, this is a
bit pessimistic but it looks like I should xfail the two failing checks.

Regarding builtins-62.c, I believe that it fails because execute_cse_sincos_1()
doesn't do the cexpi optimization:

  /* Simply insert cexpi at the beginning of top_bb but not earlier than
     the name def statement.  */
  fndecl = mathfn_built_in (type, BUILT_IN_CEXPI);
  if (!fndecl)
    return;

Same for builtins-61.c.  fold_builtin_cexp() doesn't do its stuff because:

  ifn = mathfn_built_in (rtype, BUILT_IN_CEXPI);
  if (!ifn)
    return NULL_TREE;

It looks like the failing checks in these two tests should also be xfailed.

Thoughts?
