[PATCH, testsuite]: Some random fixes for 32bit x86 targets

[Uros Bizjak]

Hello!

2015-04-29  Uros Bizjak  <ubiz...@gmail.com>

    * g++.dg/ipa/devirt-28a.C: Require LTO effective target.
    * g++.dg/ext/sync-4.C (dg-additional-options): Use -march=pentium
    for 32bit x86 targets.
    * gcc.dg/pr36504.c (dg-additional-options): Use -march=i686 -msse
    for 32bit x86 targets.
    * gcc.dg/pr39455.c (dg-additional-options): Ditto.
    * gcc.dg/pr45352-1.c (dg-additional-options): Ditto.
    * gcc.dg/pr63914.c (dg-additional-options): Use -msse
    for 32bit x86 targets.

Tested on x86_64-linux-gnu {,-m32}  and committed to mainline SVN.

Uros.
