Now FE IR -> BE IR transformation is performed in multiple stages
controller by Fir2IrConverter. Stages are
* files & classes registration
* supertypes & type parameters handling
* functions & properties signature generation
* body generation
After each step we have guarantee (with exception of local classes &
type inference combination, and external symbols) that required symbols
(class/function/property/variable/type parameter)
are already bound to real declarations and have correct parents.
This commit also fixes incorrect parents for local classes
When a local function is captured, corresponding field accesses are
later transformed by the inliner. It doesn't have enough information to
restore the original semantics completely, so it has to rely on field
names. Local functions can be overloaded or can have names matching
local variable names, in both cases we generated fields with the same
name for captured values.
Now, we use the same '$<local-class-number>' suffix for field names for
local functions as it is present in the corresponding local class name.
This allows to distinguish captured local functions from captured local
variables and between different overloads of a function with the same
name.
