[testsuite, i386] Avoid finite in gcc.target/i386/avx512dq-vfpclasspd-2.c etc.

[Rainer Orth]

Some AVX512DQ tests are failing on Solaris/x86 with gas:

FAIL: gcc.target/i386/avx512dq-vfpclasspd-2.c (test for excess errors)
FAIL: gcc.target/i386/avx512dq-vfpclassps-2.c (test for excess errors)
FAIL: gcc.target/i386/avx512vl-vfpclasspd-2.c (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/i386/avx512dq-vfpclasspd-2.c:24:20:
 warning: implicit declaration of function 'finite' 
[-Wimplicit-function-declaration]

finite() is non-standard and requires <ieeefp.h> on Solaris.  Instead of
this, I believe it's simplest to just use __builtin_finite instead.

The following patch does just that.  Tested with the appropriate runtest
invocation on i386-pc-solaris2.11 and x86_64-unknown-linux-gnu.

Ok for mainline?

        * gcc.target/i386/avx512dq-vfpclasspd-2.c (check_fp_class_dp): Use
        __builtin_finite instead of finite.
        * gcc.target/i386/avx512dq-vfpclassps-2.c (check_fp_class_sp):
        Likewise.
