b0283611e4 fix issue 798 
cannot allocate an audomatic temp
while real registers are allocated.
there is a chance that the automatic
will be allocated to one of the
allocated registers. the fix is to
not registerize such variables.

83cd4ee070 6g: generate string data as individual symbols,

also, for short strings, generate DUPOK global
