ed4f4fbfba Mark mayLoad, mayStore for insns correctly and use them 
to check if an insn is accessing memory during mem sel optimization.

0608b49819 Detect calls to compiler intrinsics and emit an extern declarations 
only for those. These extern declarations to intrinsics are currently 
being emitted at the bottom of generated .s file, which works fine with
gpasm(not sure about MPSAM though).
PIC16 linker generates errors for few cases (function-args/struct_args_5) if you do not include any
extern declarations (even if no intrinsics are being used), but that
needs to be fixed in the linker itself.

d8d27f4a4b Emit banksel and movlp instructions. 
Split large global data (both initialized and un-initialized) into multiple sections of <= 80 bytes.
Provide routines to manage PIC16 ABI naming conventions.
