This fixes several bugs in the shared-memory implementation and adds TLS relocations which was the last component required to get the shared-memory linker feature fully working.
With this PR, we can now use the self-hosted WebAssembly linker to link the threading example from: #16207 (i.e. appending
-fno-LLD
to the listed command).
