Johnni Winther 2528bf8666 [kernel] Add VariableDeclaration.isHoisted
This flag is set when a variable declaration is moved earlier in
order to be available for subsequent code that couldn't contain
its declaration. For instance variables declared in patterns which
needs to be declared before the matching expressions that initialize
them.

Johnni Winther f343c3ceb7 [cfe] Split cached expressions by receiver type
This splits cached expression by receiver type such that the initializing
expression for a cached variable isn't stored in the late variable
initializer, if it can be obtained in different ways. For instance having
both a list pattern and a map pattern in the same switch will trigger
caching of the .length property but obtaining expression differ base on
the receiver type, in the first case List.length and in second case
Map.length.
