* Do not set pi_needs_got in current_procinfo.flags at the node level, since the GOT usage can only be estimated there. Instead set the pi_needs_got flag at places where the GOT register is accessed during the code generation. This eliminates generation of the unneeded initialization of the GOT register and fixes linker errors when the _GLOBAL_OFFSET_TABLE_ symbol is referenced but no actual GOT references are present.

* 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.

* x86: clean up and place jump tables into sec_rodata on all targets. Effectively it does not change anything, because sec_rodata with relocations still go into writable data at assembler level.
