- rm tcg8086.g_maybe_got_init as it's of no use for the i8086

- rm NR_PIC_OFFSET_REG from i8086/cpubase.inc, because it isn't used (and shouldn't be used) on the i8086

-rm BX from i8086's saved_stadard_registers array, as it interferes with returning int64 in ax:bx:cx:dx and it shouldn't be saved anyway
