[testsuite] Properly XFAIL gcc.dg/vect/slp-multitypes-2.c on Solaris 2/SPARC

I noticed that gcc.dg/vect/slp-multitypes-2.c is failing on Solaris
8/x86 with Sun as:

FAIL: gcc.dg/vect/slp-multitypes-2.c (test for excess errors)
WARNING: gcc.dg/vect/slp-multitypes-2.c compilation failed to produce executable

Excess errors:
Assembler: slp-multitypes-2.c
        "/var/tmp//ccmA7WBi.s", line 16 : Illegal mnemonic
        "/var/tmp//ccmA7WBi.s", line 16 : Syntax error

        unpcklpd %xmm0,%xmm2

This should be dealt with by the explicit
check_vect_support_and_set_flags in vect.exp, which does

    } elseif { [istarget "i?86-*-*"] || [istarget "x86_64-*-*"] } {
        lappend DEFAULT_VECTCFLAGS "-msse2"
        if { [check_effective_target_sse2_runtime] } {
            set dg-do-what-default run
        } else {
            set dg-do-what-default compile
        }

Unfortunately, this gets overridden by the explicit 

/* { dg-do run { xfail { sparc*-*-* && ilp32 } } } PR rtl-opt /46603 */

To fix this, I've changed the testcase to use dg-xfail-run-if instead.
Besides, I see the failure only with gas, not Sun as.

The following patch has been tested with the appropriate runtest
invocations on both i386-pc-solaris2.8 and sparc-sun-solaris2.10 (both
as and gas).

I'm about to commit this to mainline.  The 4.5 branch is unaffected, but
4.6 is.  Ok there, too, after testing?

Thanks.

	* gcc.dg/vect/slp-multitypes-2.c: Replace dg-do run with
	dg-xfail-run-if.
	Only xfail with gas.

Ok.
