tests(benchmark): add missing scenario and optimization

[LouisTsai-Csie]

🗒️ Description

Enhance the code generator for BenchmarkTest wrapper:

• Add initial balance setting for JumpLoopGenerator, which already supports in the other code generator, this could simplify test_create.
• Add safety checks for ExtCallGenerator, when calculating the max iterations, it should deduct the stack delta that comes from setup section, or it might lead to stack overflow issue.
• Most of the contract will be filled with repeated pattern, this PR further fills the remaining space with STOP opcode. This could help simplify some cases like test_codecopy & test_return_revert.
• For ExtCallGenerator, there are two different account: target contract and loop contract. The loop contract will repeatedly calls into target contract via STATICCALL. For some operations that involves CALLDATA interactions, we should forward the CALLDATA from loop contract to target contract via (1) forward the CALLDATA from loop contract and (2) Configure the memory from CALLDATA in target contract.

Test Case Enhancement:

• test_ext_account_query_warm: Add initial balance / initial storage parametrization.
• test_blockhash: Add extra cases for fixed block index and dynamic block index
• test_pc_op: Add missing benchmark test
• test_keccak: Add this case to parametrize memory size / offset for gas repricing effort.
• test_tload: Optimize the benchmark by switching to ExtCallGenerator
• test_block_full_of_ether_transfers: Add scenario that the receiver is not an empty account.

✅ Checklist

• All: Ran fast tox checks to avoid unnecessary CI fails, see also Code Standards and Enabling Pre-commit Checks:

  uvx tox -e static

• All: PR title adheres to the repo standard - it will be used as the squash commit message and should start type(scope):.
• All: Considered adding an entry to CHANGELOG.md.
• All: Considered updating the online docs in the ./docs/ directory.
• All: Set appropriate labels for the changes (only maintainers can apply labels).
• Tests: Ran mkdocs serve locally and verified the auto-generated docs for new tests in the Test Case Reference are correctly formatted.
• Tests: For PRs implementing a missed test case, update the post-mortem document to add an entry the list.
• Ported Tests: All converted JSON/YML tests from ethereum/tests or tests/static have been assigned @ported_from marker.

Cute Animal Picture

We miss the benchmark for PC opcode

[LouisTsai-Csie]

Instead of finding the optimal length, add a new case that parametrized initial memory layout and access offset. Request by gas repricing effort.

[LouisTsai-Csie]

Add a new scenario for ether transfer benchmark: whether the receiver is an empty account.

[LouisTsai-Csie]

Adding extra BLOCKHASH operation for benchmarking, as it was one of the slowest operations.
Cases:

• Valid block index
• Invalid block index
• Dynamic block index

[LouisTsai-Csie]

Add new test scenario for gas repricing effort:

• Accessing empty / non-empty account
• Accessing account contains zero / non-zero balance
• Accessing account contains zero / non-zero storage

Thanks!

In general, I liked the refactoring and changes, I've just left comments on multiple files just to make everything more polished.

[LouisTsai-Csie]

Sorry for adding complexity to this PR, I’ve added one more commit that optimizes the DUP and CALLDATASIZE operations.

• test_dup: The setup stack delta is now handled in ExtCallGenerator, which simplifies the test logic.
• test_calldatasize: This test is also simplified using ExtCallGenerator, as the generator now forwards calldata to the target contract.

Excellent job on all these optimizations. LGTM, thanks!
