wasm-linker: basic TLS support
Linker now parses segments with regards to TLS segments. If the name
represents a TLS segment but does not contain the TLS flag, we set it
manually as the object file is created using an older compiler (LLVM).
For now we panic when we find a TLS relocation and implement those
later.
