the result type of the expr node.
Implement isIntegerConstantExpr for ImplicitCastExpr nodes the same
was as for CastExpr nodes.
Implement proper sign/zero extension as well as truncation and noop
conversion in the i-c-e evaluator. This allows us to correctly
handle i-c-e's like these:
char array[1024/(sizeof (long))];
int x['\xBb' == (char) 187 ? 1: -1];
this implements test/Sema/i-c-e2.c
