test_calldataload_chained()

Documentation for tests/benchmark/compute/instruction/test_call_context.py::test_calldataload_chained@ffe48572.

Generate fixtures for these test cases for Bogota with:

fill -v tests/benchmark/compute/instruction/test_call_context.py::test_calldataload_chained --gas-benchmark-values 1

Benchmark CALLDATALOAD taking its offset from the previous load.

The calldata is all zeros, so every load reads offset 0. An input of 1 to 31 bytes makes every load a partial, zero-padded word.
