	Look up a symbol by name. Builds the table on first use.
mlir::Operation *	lookupSymbol (mlir::SymbolRefAttr attr)

Detailed Description

Helper to only build the symbol table when needed. Use this when performing symbol lookups inside a module walk to avoid O(n) lookups per op and pseudo-quadratic behavior in large modules.
