Removed T_XHP_ENUM. See Issue #740 (https://github.com/facebook/hiphop-php/issues/740)
Allow __get() magic methods to be called recursively. This creates the possibility of infinite-loop recursion if used messily, but fixes an Undefined Property bug occuring when a getter tried to re-enter itself with a different property name. See Issues #254 (https://github.com/facebook/hiphop-php/issues/254), #348 (https://github.com/facebook/hiphop-php/issues/384), and #657 (https://github.com/facebook/hiphop-php/issues/657).
Merge branch 'recursive_getters'
