The existing Thread Local Storage (TLS) implementation for riscv64 uses initial-exec (IE) mode, however a MOV of a TLS symbol currently loads the thread pointer offset and not the actual address or memory location. Rework TLS on riscv64 to generate the full instruction sequence needed to load from or store to a TLS symbol. Additionally, provide support for both initial-exec (IE) and local-exec (LE) TLS - in many cases we can use LE, which is slightly more efficient and easier to support in the linker.
