Local variable names not guaranteed unique within CIL method scope

[degory]

CIL assembler does not support nesting additional scopes within a method's scope. As a result multiple uses of the same local variable name within different block scopes of the same ghul function results in invalid CIL.

Need to find a way to disambiguate local variables that have the same name but different scopes.

Probably easiest just to number all variables as they're encountered, either in the declare-symbols pass or in the generate-il pass
