2cdd3b2081 Resolving Keccak-256: check if arguments are identifiers early.
Previously, the check on whether the optimization was useful gas wise was done before checking if
the keccak256 opcode had identifier as arguments. Since the gas meter crashes when encountering
certain Yul opcodes (create, dataoffset, etc.), this optimizer step crashed.

cf6fe5a777 NameDispenser: Added three public functions.
The private function `illegalName` was converted into a public function.

A new public getter function `usedNames()` returns a reference to `m_usedNames`.

A public function reset that would change all `m_usedNames` to *only* the names that are used in the
AST. Also resets the counter. This will be used before the final NameSimplifier step in the
optimization phase.

The first two functions were added so that `NameSimplifier` could use it instead of traversing the AST
using `NameCollector` to find used names.
