c642b84fb8 prefix captured value names with $ so they look like

which has the right index including chains.

e74c3bae3a Initial implementation of PIC16 Cloner pass. 
This pass is supposed to be run on the linked .bc module.
It traveses the module call graph twice. Once starting from the main function
and marking each reached function as "ML". Again, starting from the ISR
and cloning any reachable function that was marked as "ML". After cloning
the function, it remaps all the call sites in IL functions to call the
cloned functions. 

Currently only marking is being done.

bd12fe8b69 make the new isel's interpreter loop call the generated 
CheckComplexPattern function.  Though it is logically const,
I don't have the fortitude to clean up all the targets now,
and it not being const doesn't block anything.

code that handled ComplexPatterns by making EmitChildMatchCode call
