First pass at LLD support for Emscripten (#1346)
* Skeleton of a beginning of o2wasm, WIP and probably not going to be used
* Get building post-cherry-pick
* ast->ir, remove commented out code, include a debug module print because linking
* Read linking section, print emscripten metadata json
* WasmBinaryWriter emits user sections on Module
* Remove debugging prints, everything that isn't needed to build metadata
* Rename o2wasm to lld-metadata
* lld-metadata support for outputting to file
* Use tables index instead of function index for initializer functions
* Add lld-emscripten tool to add emscripten-runtime functions to wasm modules (built with lld)
* Handle EM_ASM in lld-emscripten
* Add a list of functions to forcibly export (for initializer functions)
* Disable incorrect initializer function reading
* Add error printing when parsing .o files in lld-metadata
* Remove ';; METADATA: ' prefix from lld-metadata, output is now standalone json
* Support em_asm consts that aren't at the start of a segment
* Initial test framework for lld-metadata tool
* Add em_asm test
* Add support for WASM_INIT_FUNCS in the linking section
* Remove reloc section parsing because it's unused
* lld-emscripten can read and write text
* Add test harness for lld-emscripten
* Export all functions for now
* Add missing lld test output
* Add support for reading object files differently
Only difference so far is in importing mutable globals being an object
file representation for symbols, but invalid wasm.
* Update help strings
* Update linking tests for stackAlloc fix
* Rename lld-emscripten,lld-metadata to wasm-emscripten-finalize,wasm-link-metadata
* Add help text to header comments
* auto& instead of auto &
* Extract LinkType to abi/wasm-object.h
* Remove special handling for wasm object file reading, allow mutable globals
* Add braces around default switch case
* Fix flake8 errors
* Handle generating dyncall thunks for imports as well
* Use explicit bool for stackPointerGlobal
* Use glob patterns for lld file iteration
* Use __wasm_call_ctors for all initializer functions
