Implement name mangling for lambda expressions that occur within the

default arguments of function parameters. This simple-sounding task is
complicated greatly by two issues:

  (1) Default arguments aren't actually a real context, so we need to
  maintain extra state within lambda expressions to track when a
  lambda was actually in a default argument.
  (2) At the time that we parse a default argument, the FunctionDecl
  doesn't exist yet, so lambda closure types end up in the enclosing
  context. It's not clear that we ever want to change that, so instead
  we introduce the notion of the "effective" context of a declaration
  for the purposes of name mangling.
