[Patch, testsuite] Fix some bogus testsuite failures for avr

[Senthil Kumar Selvaraj]

Hi,

  This patch requires int32plus and ptr32plus for a couple of tests,
  tweaks Wduplicated-cond-3.c to use a smaller constant that fits in
  16 bits, and marks one test as too big
  for avr.

  Committed to trunk.

Regards
Senthil

        * c-c++-common/Wduplicated-cond-3.c (fn10): Use smaller 
        const literal.
        * c-c++-common/builtin-arith-overflow-2.c: Skip for avr.
        * c-c++-common/pr68833-1.c: Require int32plus.
        * gcc.dg/ipa/pr63551.c: Likewise.
        * gcc.dg/ipa/pr63595.c: Require ptr32plus.
        * gcc.dg/ipa/pr64041.c: Require int32plus.
