- Split out relocation processing into scanRelocations
- Split out synthetic sections into their own classes.

WebAssembly depends on attributes.h which includes attributes.inc.
Unless cmake explicitly specifies this dependency, the .inc file
is sometimes generated after the build tries to use it.

In this initial version we only GC symbols with `hidden` visibility since
other symbols we export to the embedder.
We could potentially modify this the future and only use symbols
explicitly passed via `--export` as GC roots.
This version of the code only does GC of data and code. GC for the
types section is coming soon.

This file contained only a single function that was only
really needed in one place, so just inline it.

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