[WebAssembly] add: hidden option to disable slow wasm pass (#67715)
Currently for any wasm target, llvm will make a pass that removes
irreducible control flow. (See
[here](https://llvm.org/doxygen/WebAssemblyFixIrreducibleControlFlow_8cpp.html)).
This can result in O(NumBlocks * NumNestedLoops * NumIrreducibleLoops +
NumLoops * NumLoops) build time, which has resulted in exceedingly long
build times when testing. This PR introduces a hidden flag to skip this
pass, which brings some of our build times down from 30 minutes to ~6
seconds.
