[testsuite, i386] Fix gcc.target/i386/avx-vextractf128-256-5.c with Solaris as (PR testsuite/70356)

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

This patch (provided by Jakub in the PR) fixes a failure of
gcc.target/i386/avx-vextractf128-256-5.c on the gcc-5 branch with the
Solaris assembler:

FAIL: gcc.target/i386/avx-vextractf128-256-5.c (test for excess errors)

The problem is that a target selector to dg-do overrides a previous
dg-require-effective-target, causing (in this case) an attempt to
assemble avx512f insns with the native Solaris assembler that lacks
support for them.

Tested with the appropriate runtest invocations on i386-pc-solaris2.12
with both as and gas, installed on the gcc-5 branch as approved by Uros
in the PR.

As Uros requested, I've also forward-ported the testcase to mainline
where it had been forgotten, tested as before and on x86_64-pc-linux-gnu.
