ea6d1ea701 it's not safe to assume that property access is side-effect-free

exception is thrown when the expression is undefined)

92e22c460d possible optimization for AST_Undefined
if undefined is defined, ;-), we replace AST_Undefined nodes to a reference

single letter; this helps at least on jQuery.
