[cs] >>= not work if without -D erase-generics

[sonygod]

class Main {
		static function main() {
		   
			
			
			var value:cs.types.Int64= 1;
			value >>= 7;//-D erase-generics will compile ok 
			
			
		}
	}

This is compiled to

long @value = ( (long) (1) );
@value >>= ( (long) (7) );

which is wrong, because 1 and 7 are typed as Int in AST. Removing those (long) fixes native compilation.

Works fine in 3.4.7, so it's a regression
