[PATCH, testsuite]: Move x86 specific tests to gcc.target/i386 directory

[Uros Bizjak]

... and add ifunc effective target requirement where necessary.

2015-11-03  Uros Bizjak  <ubizjak@gmail.com>

    * gcc.dg/mvc1.c: Move to ...
    * gcc.target/i386/mvc1.c: ... here.  Require ifunc.
    * gcc.dg/mvc2.c: Move to ...
    * gcc.target/i386/mvc2.c: ... here.
    * gcc.dg/mvc3.c: Move to ...
    * gcc.target/i386/mvc3.c: ... here.
    * gcc.dg/mvc4.c: Move to ...
    * gcc.target/i386/mvc4.c: ... here.  Require ifunc.
    * gcc.dg/mvc5.c: Move to ...
    * gcc.target/i386/mvc5.c: ... here.
    * gcc.dg/mvc6.c: Move to ...
    * gcc.target/i386/mvc6.c: ... here.
    * gcc.dg/mvc7.c: Move to ...
    * gcc.target/i386/mvc7.c: ... here.

    * g++.dg/ext/mvc1.C: Require ifunc.

Tested on x86_64-linux-gnu {,-m32} CentOS 5.11 (no ifunc
functionality) and committed to mainline SVN.
