20c51be30c The cloner has nothing to do if any of the main or ISR entrypoints are not
present in the module.

651d85c2f2 Currently in LLVM, names of libcalls are assigned during TargetLowering
object construction. There is no provision to change them when the 
code for a function generated. 
So we have to change these names while printing assembly.

94c3ddbcc6 Added routine to clone the body of a function and maintain a map of already
cloned functions.

139eda6054 Added a function to clone locals of a function.( which for pic16 are globals
with mangled names).

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.
