The second testcase FAILs on both x86_64 and i686, because it contains
no dg-options, therefore is compiled with -ansi -pedantic and that doesn't
allow GNU inline asm syntax.  While looking at the testcase, I believe you
meant to make it executable, otherwise I don't understand why it has been
added in this form, and while at it, I've also fixed it for -masm=intel.

Tested on x86_64-linux and i686-linux, committed to trunk.
