emsdk list fixes (#257)

Browse Source 
List the recommended downloads (latest, latest-upstream) first, and with version and hash. Then list precompiled things, then list build-from-source things.

Remove old upstream-clang build from source, which has been incorrect since llvm switched to a monorepo anyhow. If we want the emsdk to support source builds of llvm, we'll need to fix that - however, as we can use plain upstream llvm anyhow, that shouldn't be hard for developers to build themselves (and normal users will get a precompiled version anyhow).

Remove the option to build fastcomp from source with wasm backend support, as it is horribly old there.

Noticed these issues in emscripten-core/emscripten#8728
