Copy and load instructions with OOB offsets

[OlivierBBB]

We want to test that out of bounds CDL returns 0, as expected, on the stack. We further want to test if out of bounds CDC performs the correct right 0-padding. The picture below is incomplete, as it describes only as subset of the test cases. In particular, we must test the mixed case where the output is both call data and 0-padding. Furthermore, the relevant opcodes are:

• CALLDATALOAD
• CALLDATACOPY
• CODECOPY
• EXTCODECOPY
