Add more kinds to KIND_OP

Eleven kinds, all tier-1 counterparts of existing tier-2 uops or of open
specialization proposals:

- UNARY_NEGATIVE_INPLACE: negate a uniquely referenced float in place
  (UNARY_NEGATIVE gains an inline cache)
- BINARY_OP_TRUEDIV_FLOAT: float / float when the operands are shared
- BINARY_OP_FLOOR_DIVIDE_INT, BINARY_OP_REMAINDER_INT: compact ints,
  nonzero divisor, floor semantics
- BINARY_OP_LSHIFT_INT, BINARY_OP_RSHIFT_INT: compact ints, shift count
  within range
- BINARY_OP_SUBSCR_BYTES_INT, BINARY_OP_SUBSCR_BYTEARRAY_INT,
  STORE_SUBSCR_BYTEARRAY_INT: byte access with a compact in-range index
- UNPACK_SEQUENCE_STEAL_TWO_TUPLE, UNPACK_SEQUENCE_STEAL_TUPLE: a tuple
  referenced only from the stack gives up its items without refcount
  traffic; a shared tuple takes the increfing path
