eliminate CALL_SIMPLE_METHOD

Arrange operands of several opt_something insns so that jumps to
opt_send_without_block can be applied to them. This makes it
possible to eliminate CALL_SIMPLE_METHOD macro at all.  Results
in binary size of vm_exec_core to change from 27,008 bytes to
26,016 bytes on my machine. [close GH-1779]

Note however that PC can point somewhere non-instruction now.
