[Patch, testsuite] Require int32plus and scheduling support for some tests

[Senthil Kumar Selvaraj <senthil_kumar dot selvaraj at atmel dot com>]

Hi,

  This patch add dg-require-effective-target directives to a few tests
  that were failing unnecessarily for the AVR target.

  One of them invokes the compiler with -fschedule-insns2 - I've
  required scheduling support for that testcase. For all other tests,
  I've required int32plus - they either use bit shifts wider than
  16 bits (AVR's int size), or use int constants that are too big
  for a 16 bit int.

  If ok, could someone commit please? I don't have commit access.

Regards
Senthil
