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.

32ba5f5ae7 libsolidity: Extend the AST for named AST nodes in order to get precise locations for names.
The actual SourceLocation on an ASTNode is representing the whole
ASTNode whereas in an LSP (for example) you are also interested in the
SourceLocation of a name of a construct (e.g. variable decarlation, function definition, ...).

This also properly encodes non-existend sources as `-1` in the JSON output (eliminating the use of `numeric_limits<size_t>::max()`).
