function cause string1.c regression test fails

and onStack flag is cleared,
* (pic16_popGetTempReg, pic16_popReleaseTempReg): modified to
copy temporary pcodeop,
* (genPcall): added warning for not updating PCLATU,
* (genFunction): removed test with IFFUNC_CALLEESAVES, its
always true for pic16 port,
* (genMultOneWord): NEW, supports integer multiplication,
* (genMult): modified to call genMultOneWord,
* (ifxForOp): added warning when return NULL,
* src/pic16/glue.c (pic16emitRegularMap): symbol implicit
flag is set before call to operandFromSymbol for implicit
added structures,
* src/pic16/main.c (_pic16_finaliseOptions): options.float_rent,
options.intlong_rent are set by default,
* (_hasNativeMulFor): modified to allow port generation of integer
multiplication,
* src/pic16/ralloc.c (pic16_allocDirReg): commented out line which
set regtype to REG_SFR for all registers, restricting seting the
accessBank flag for registers 0<= r < 0x80 and 0xf80<=r<=0xfff,

checking if symbol is already in set,

* src/pic16/gen.c: (_G): added entry interruptvector,
* (assignResultValue): removed some commented out lines,
* (genFunction): check for ISR via sym->type, absolute section for
interrupt code is created via a new pBlock, the goto instruction is
placed now correctly at the interrupt vector position, changed all
references from ivec to _G.interruptvector,
* WREG,STATUS,BSR are not saved in stack upon an entry to interrupt
is the interrupt is a high priority one, same for return from ISR,

externs to calls of checkAddSym,

will only be emitted if pic16_pcode_verbose flag is set,

comparing, improved the aboslute section creation for ISRs,
added FSR0L/FSR0H in registers that are saved in an ISR,
* (genInline): fixed the processing of inline snippets,
now they undergo no process by the peephole optimizer
* src/pic16/glue.c (pic16emitRegularMap): symbols with initialiser
are placed in idataSymSet,
* (pic16emitStaticSeg): extern symbols are added in externs,

switching when aboslute variables are placed in access bank memory

* (packRegsForSupport,packRegsForAccUse,packRegsForOneuse):
commented out with #if,

symbols are not correctly handled,

pCodeInstruction instead of pCode,
* src/pic16/pcode.c (pic16_newpCodeAsmDir): modified for the new
pCodeAsmDir definition,
* (pic16_pCode2str, genericPrint): when an AsmDir pcode has a NULL
directive, then the argument directive is emitted without the leading
tab, hack for inline labels which must be in the first column,

* (pic16_findPrevInstruction): added case for PO_ASMDIR,

instead of "RETLW" for init data
* src/pic16/ralloc.c (pic16_allocDirReg): warning when a symbol is
not IN_DIRSPACE, work around to reduce bank switching when aboslute
