reference to a deprecated symbol _GPTRREG was causing failure to
link. Thanks G. M. Gallant for the info.

* src/pic16/device.c (pic16_dump_gsection,
* pic16_groupRegistersInSection): handle symbols declared to be in
access bank differently,
* src/pic16/gen.c (struct _G): added field resDirect,
* (aopForSym): if symbol on stack and iCode is '=' and result exists,
send values read from stack directly to result and don't allocate
temporary values,
* (pic16_sameRegs): fixed bug that allowed MOVFF to move between
same registers,
* (pic16_sameRegsOfs): NEW,
* (freeAsmop): if _G.resDirect is set then do not mark registers as
free because they were not allocated from temporary pool,
* pic16_popRegFromString): workaround to fix a problem with
allocating variables twice or never,
* (genGenPointerGet): using PRODL instead of FSR0H,
* (genGenPointerSet): using POSTDEC1 (that is a stack location)
instead of FSR0H,
* (genAssign): take advantage of the _G.resDirect flag,
* (genCast): around line 11844, use mov2f instead of directly
MOVFF'ing between operands to account for literal values,
* src/pic16/genutils.c: some new debug functions for gpsim have been
added,
* src/pic16/glue.c (pic16_printIvalType): fixed bug that initialized
float with integer part only,
* src/pic16/main.c (_process_pragma): handle pragma udata access to
place variables in access bank
* device/lib/pic16/libsdcc/gptr/gptr*.c: using BRA instead of GOTO,
updated sources to reflect recent changes in gen.c
