[issue19219] speed up marshal.loads()

[Kristján Valur Jónsson]

Kristján Valur Jónsson added the comment:

Right, in this case, memory copying is avoided.

Regarding the memoing of 0, empty tuple, etc:
Special opcode may still benefit because it takes only one byte.  So, you save four bytes for each such case.  I think it might be worth investigating.
