Specifically add support for custom sections that contain
relocations, and for the two new relocation types needed
by DWARF sections.

Copy user-defined custom sections into the output, concatenating
sections with the same name.

SubSection inherited from SyntheticSection, and SyntheticSection inherits
from OutputSection, so SubSection was an OutputSection. But that's wrong
because SubSection is not actually a WebAssembly output section.
It shares some functionalities with OutputSection, but overall it's very
different.
This patch removes that inheritance.

Summary:
- Makes code more in line with LLVM style (e.g. const char * -> StringRef)
- Do not use formatv since we can construct message just by `+`
- Replace some odd types such as `const StringRef` with more common type
- Do not use default arguments if they are not necessary

The code section is now written out one function
at a time rather than all the functions in a given
objects being serialized at once.
This change lays the groundwork for supporting
--gc-sections.

Store data relocations with their respective segment.
This allows relocations to be applied as each segment
is written (and therefore in parallel).

This change add support for init functions in the linking
section, but only in -r/--relocatable mode.

This linker backend is still a work in progress but is
enough to link simple programs including linking against
library archives.
