Bug 1639153 - Part 6.2: Establish dependency from tls for x86 callWithABI div/mod i64. r=lth
x86 has few register so to do div/mod for i64 it call the runtime
and clobber almost all gp registers including WasmTlsReg.
To be able to call c++ runtime via Builtin thunk we need to set up WasmTlsReg.
In this patch I create dependencies from MIR level to Codegen to be sure that WasmTlsReg is alive
when we call runtime.
