Rollup merge of #54258 - alexcrichton:lld-fatal-warnings, r=eddyb
Enable fatal warnings for the wasm32 linker Historically LLD has emitted warnings for various reasons but all the bugs have since been fixed (yay!) and by enabling fatal warnings we should be able to head off bugs like #53390 sooner.
