patch fixing a test for PR55151

[Vladimir Makarov]

   The following patch adds omitted target for the test.  The test was 
supposed to run on x86-64 only.  On 32-bit x86, it should fail.  Reload 
fails on this test on x86 too although with an error message.  I am 
going to add a generation of a message too.

   Committed as rev. 193311.

Checking x86_64-*-* target is incorrect since i686 GCC can support
64-bit.  You should check !ia32 target:

/* { dg-do compile { target { ! { ia32 } } } } */

Thanks, H.J.  I've just fixed it.

Lots of constraints there that might not be suitable for all
machines.  Unless it's expected to pass (almost) everywhere, it
should move to gcc.target/i386.

If it *is* expected to pass everywhere,
at least add /* { dg-require-effective-target fpic } */
or similar (can be done in the target expression).

I am agree it is better not to run it on any target.  I've moved it to 
gcc.target/i386.

Thanks for pointing this out.
