Emit a method declaration.

<p>A {@code null} return type may be used to indicate a constructor, but
{@link #beginConstructor(Set, String...)} should be preferred. This behavior may be removed in
a future release.

@param returnType the method's return type, or null for constructors
@param name the method name, or the fully qualified class name for constructors.
@param modifiers the set of modifiers to be applied to the method
@param parameters alternating parameter types and names.
