    * gcc.dg/ifcvt-1.c: Compile also for 64-bit i?86-*-* target.
    * gcc.dg/ifcvt-2.c: Ditto.
    * gcc.dg/zero_bits_compound-1.c: Ditto.
    * gcc.dg/zero_bits_compound-1.c: Ditto.
    * gcc.dg/pr40550.c: Simplify target selectors.
    Use dg-additional-options.
    * gcc.dg/pr47893.c: Ditto.
    * gcc.dg/pr68435.c: Compile also for i?86-*-* target.  Add -march=i686
    additional options for 32-bit x86 targets.
    * gcc.dg/pr70955.c: Move to ...
    * gcc.target/i386/pr70955.c: ... here.  Simplify target selector.

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

Uros.
