down to pass builder in ltobackend.
Currently CodeGenOpts like UnrollLoops/VectorizeLoop/VectorizeSLP in clang
are not passed down to pass builder in ltobackend when new pass manager is
used. This is inconsistent with the behavior when new pass manager is used
and thinlto is not used. Such inconsistency causes slp vectorization pass
not being enabled in ltobackend for O3 + thinlto right now. This patch
fixes that.

Major refactor to better match the structure of the ELF linker.
- 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.

Without this the LLVM_BUILD_LLVM_DYLIB+DLLVM_LINK_LLVM_DYLIB build
break.
Also remove unneeded lldCore from wasm/CMakeLists.txt

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.
