Sam Clegg	53217ecb88	[lld][WebAssembly] Don't apply data relocations at static constructor time ... Instead, export `__wasm_apply_data_relocs` and `__wasm_call_ctors` separately. This is required since user code in a shared library (such as static constructors) should not be run until relocations have been applied to all loaded libraries.

Sam Clegg	ef8c9135ef	[WebAssembly] Allow import and export of TLS symbols between DSOs ... We previously had a limitation that TLS variables could not be exported (and therefore could also not be imported). This change removed that limitation.

Sam Clegg	bda8b84884	[lld][WebAssembly] Disallow exporting of TLS symbols ... Cross module TLS is currently not supported by our ABI. This change makes explicitly exporting a TLS symbol into an error and prevents implicit exporting (via --export-all).
