Left-leaning red-black tree data structure
Implement library functions for "left-leaning red-black trees" with
uint64_t keys. This is meant for looking up symbols by address in the
backends that need to do so, e.g. ELF.
A good question is if there is a better way to do this, that recovers
the original symbol, but that's a future issue.

ELF64: GOTOFF64 doesn't need a gsym at all
GOTOFF64 is used for local variables (as a 64-bit offset from the GOT;
only needed in the Medium PIC or Large PIC models.) It therefore
should *not* be a elf_add_gsym_reloc() invocation.

ELF64: We apparently don't need exactitude for GOTOFF64
I am having a bit of a hard time understanding the proper operation of
the "exact" flag to elf_add_gsym_reloc(). We apparently won't
generate proper GOTOFF64 relocations with this flag set; it is
possible that there are *no* proper uses of this flag. This clearly
needs to be figured out.

ELF64: GOT and PLT references need a symbol (a slot!) to reference
GOT and PLT references need a symbol; after all, they reference a GOT
or PLT slot. Thus, they need elf_add_gsym_reloc(). Mungify the
interface so that they can communicate the need for the PC-shifted
offset into the relocation.

ELF64: unbreak generating no-segment addresses
When generating an address that is *not* tied to a symbol, we just
want to emit the bytes. I believe the assembler is already supposed
to do that for us, but just in case, do it right here too.

ELF64: use the RELA addend field instead of relying on the code stream
The x86-64 ABI wants the symbol addend to reside in the addend field
of the RELA relocation, not in the code stream. Apparently it's
something one can get away with, but the linker would still botch it
for some cases. Change it so we pass the proper output and emit zero
into the code stream.

In addition, a fix has been made to the corresponding

Both of these areas still need additional testing.
