optimization scheme to compansete for instruction overhead between
same iCodes, this scheme is currently under development and is not

to && operator,

* src/SDCCicode.c (geniCodeJumpTable): Better logic to determine if a
a jump table is the best form for a switch statement, including
automatic insertion of missing cases to make the case range
continuous. Developed in collaboration with Frieder Ferlemann.
* src/pic16/gen.c (genPackBits): added operand right in function
parameters, load result directly if p_type is POINTER (that is
called by genNearPointerSet)
* (genUnPackBits): added operand left in function parameters,
* (genNearPointerGet, genNearPointerSet): prevent the loading of
FSR0 if accessing bitfields,
