* Use GOT-relative constants for i386 PIC jump tables, they don't need runtime relocations. Now almost ABI-compliant on Linux/BSD (Darwin targets unchanged). Also clean up i8086-specific stuff: using tai_const.create_type_sym(aitconst_ptr,...) generates near pointers on i8086, which is the desired goal.
