Fix gcc.dg/tree-ssa/pr59597.c failure for avr

Browse Source 
Declare loop index variable j as a 32 bit int instead of assuming ints 
are 32 bits. The smaller int size on the avr makes prior passes optimize
away the loop exit check (j < 10000000), as the constant is outside
the range of a 16 bit int.
