[Patch, testsuite] Fix bogus pr31096-1.c failure for avr

[Senthil Kumar Selvaraj]

Hi,

  This patch fixes a bogus testsuite failure (gcc.dg/pr31096-1.c) for
  the avr target.

  The dump expects constants which would only be present if the target's
  int size is 32 bits.

  Fixed by explicitly using 32 bit ints for targets with __SIZEOF_INT__
  < 4. Committed to trunk as obvious.

Regards
Senthil

        * testsuite/gcc.dg/pr31096-1.c: Use __{U,}INT32_TYPE__ for
        targets with sizeof(int) < 4.
