The m (multiline) and s (dotall) flags just needed to be marked as allowed; the required logic was already in the regexp parser. A regexp /<x>/ without the y (sticky) flag is equivalent to the sticky regexp /.*?<x>/y. The interpreter now assumes that every regexp is sticky, and the compiler appends a preamble corresponding to /.*?/ before non-sticky regexps. To reuse existing code for compiling this preamble, the logic for each kind of quantifier is now in a separate function and called from VisitQuantifier and for the preamble. The commit also includes some improvements/fixes for character ranges: - Empty character ranges/disjunctions should never match, but before this commit they would *always* match. - The check of the range bounds in CanBeHandledVisitor was unncessary; without the unicode flag this can't be a range that can't be specified in 2-byte codepoints, and once we support unicode we simply support all codepoints. - The capacity of the list containing the complementary intervals of a character range is now calculated more accurately.
