[testsuite] Fix gcc.target/i386/avx512f-vrndscaless-2.c on Solaris 9/x86

[Rainer Orth]

gcc.target/i386/avx512f-vrndscaless-2.c currently FAILs on Solaris 9/x86
with gas:

FAIL: gcc.target/i386/avx512f-vrndscaless-2.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/i386/avx512f-vrndscaless-2.
c:21:14: warning: incompatible implicit declaration of built-in function 'floorf
' [enabled by default]
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/i386/avx512f-vrndscaless-2.
c:24:14: warning: incompatible implicit declaration of built-in function 'ceilf'
 [enabled by default]

The platform lacks C99 support, but this can easily be avoided by using
the builtins instead.  The following patch does just that; tested
with the appropriate runtest invocation on i386-pc-solaris2.9 and
x86_64-unknown-linux-gnu.

Ok for mainline?

        * gcc.target/i386/avx512f-vrndscaless-2.c (compute_rndscaless):
        Use __builtin_floorf, __builtin_ceilf.
