Prior to this commit, ControlFlowPointcut supported a single method
name which was matched exactly. Although it was possible to extend
ControlFlowPointcut to add support for pattern matching, it was a bit
cumbersome.
To address that, this commit introduces built-in pattern matching
support for method names in ControlFlowPointcut, analogous to the
pattern matching support in NameMatchMethodPointcut.
Specifically, a user can provide one or more method name patterns, and
the patterns will be matched against candidate method names using OR
semantics.
By default, the matching algorithm delegates to
PatternMatchUtils.simpleMatch(), but this can be overridden in
subclasses by overriding the new protected isMatch() method.
