8f3afbc621 Emulate the current isel's "IsChainCompatible" logic for now.
I'd like to eventually rip it out, but for now producing the
same selections as the old matcher is more important.

a6df2a60e5 prefix captured value names with $ so they look like
variables.  Use the fancy OpNo variable instead of i,
which has the right index including chains.

6e98127ab8 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.

9625fb062a 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.
