Improve code generation for shift word: add intrinsics for fixnum-shift-fast in the case where the shift count is not constant, transform 1 swap shift into a more overflow check with open-coded fast case, transform bitand into fixnum-bitand in more cases

define-partial-eval framework in propagation pass makes it easy to add transforms; moving some transforms from stack checker to propagation, making them stronger
