Regenerate std/opcodes.solc (via gen-std-opcodes.py) to match the Primitives.hs Yul builtin list as of EVM Osaka: Add clz (0x1e, EIP-7939). Co-authored-by: Alex Beregszaszi <alex@rtfs.hu>

changed the title
hullBuiltins (the type environment yule uses to typecheck Hull objects) had diverged from Primitives.hs/std/opcodes.solc: - extcodecopy took 3 args; the Yul builtin is extcodecopy(addr, dst, offset, length) = 4 args. Any use produced an arity-mismatch error. - clz (Osaka, EIP-7939) was missing. - blobhash (Cancun, EIP-4844) was missing, despite blobbasefee being present (inconsistent partial-Cancun support). - datacopy (Yul object builtin) was missing, diverging from Primitives. difficulty was already present and left unchanged.
Matches Primitives.hs, which exposes only prevrandao (post-Merge name) and not the deprecated difficulty alias.
These low-level control-flow opcodes are not part of the user-facing Yul dialect and were unused: no codegen path (EmitHull, yule Translate) emitted them and no source called them. Dropping them keeps hullBuiltins in parity with Primitives.hs/std/opcodes.solc. The hull->yul side (builtinFuns in yule/TM.hs) never referenced them, so no change there.

In std/opcodes.solc, it may be worthwhile to add a comment along the lines
