beam_block: Remove a clause that will never be executed
Since the introduction of literals in R12B, empty tuples are literals. Thus the put_tuple/2 instruction is always followed by at least one put/1 instruction. Therefore the alloc_may_pass/1 function in beam_block no longer needs a clause for for "put_tuple", because the clause for "put" will always be reached first (since the instruction stream is scanned in reverse execution order). Note that if the compiler would generate a "put_tuple 0 Dst" instruction for some unfathomable reason, we should still be because the run-time system will now refuse to load a module containing such an instruction.
