lea rax, [var wrt rip] ; generates RIP-relative insn and REL32 reloc

and not:
mov rcx, [var+rbx] ; generates ADDR32 reloc

on the symbols that are actually used by relocs, but having them there
doesn't hurt linking; it only exposes all of the internal symbol names.
With these changes, yasm output matches the new ML64 output except for a
very few cases:
- ML64 generates REL32 relocs when referencing objects in the same .text
section. I cannot see how this is necessary because call instructions
don't generate REL32 relocs! I currently do not plan on fixing this unless
it causes a problem.
- ML64 generates ADDR32 relocs instead of REL32 relocs when loading a
32-bit register with the address of an object. I will probably try to fix
this.
