Extend the EVM JIT linear memory precheck planner to cover repeated MSTORE8 write motifs. Reuse the existing block precheck plan with AccessWidth=1 so byte writes can share one memory proof across the block. Previously, dynamic MSTORE8 recurrences still normalized and prechecked memory per opcode while MLOAD and MSTORE could consume a shared linear block precheck.

Apply clang-format to the MSTORE8 linear precheck visitor condition so the CI format check accepts the PR.
