RFR (S): Issue constants to constant pool in stub code

[Lindenmaier, Goetz]

Hi Vitaly,

What about "not in code?"

Thanks,
  Goetz.

Hi Goetz,

I think the assert message in assembler.cpp (line 107) needs adjustment since cs can also be stubs now.

Thanks

Hi,

When adding constants to the constant pool, the code_section is switched
to the constant pool code_section, and then back again.  It was hard coded
to switch back to the code_section for code.
If constants are issued in stubs, it is switched back to the wrong code section.
I changed the code to remember the code section and switch back to the proper
one.
Further it's necessary to relocate only after copying code and stub section to
a new location, as the relocation might affect an address in the stub section.

You can find these changes here:

or in our ppc port:

Thank you and best regards,
  Goetz
