Description:
------------
if float or string is casted to an integer type and it evaluates to a number outside the max. range, at least warning should be emitted

Test script:
---------------
var_dump((int) (PHP_INT_MAX + 1));    // int(-9223372036854775808)
var_dump((int) (PHP_INT_MAX + 10));   // int(-9223372036854775808)
var_dump((int) (PHP_INT_MAX + 2000)); // int(-9223372036854773760)
var_dump((int) INF);                  // int(0)

Expected result:
----------------
all 4 cases must emit at least a warning, similar to 1/0 division
