Documentation for tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_block_2d_gas_accounting.py::test_block_gas_used_execution_dominates@26332146.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_block_2d_gas_accounting.py::test_block_gas_used_execution_dominates --fork Amsterdam

Verify block.gas_used = block_execution_gas when state gas is zero.

A block containing only STOP transactions to existing contracts produces no state gas. The block header gas_used must equal the sum of execution gas across all transactions, since max(execution, 0) = execution.
