  -----------
  [lld][WebAssembly] Generate TLS relocation code also when linking statically

Previously relocations were only generated for PIC output, but
relocations for TLS GOT entries are always needed when shared
memory is enabled, not just in PIC mode.

This means that the `__wasm_apply_global_tls_relocs` is now
generated even for statically linked (non-PIC) output.  Without
this the globals that hold the addresses of TLS symbols are
not set correctly.
