cmd/compile: graceful handle error in noder LoadPackage

Browse Source 
When syntax.Parse returns error, noder.file will be nil. Currently, we
continue accessing it regardlessly and depend on gc.hidePanic to hide
the panic from user.

Instead, we should gracefully handle the error in LoadPackage, then exit
earlier if any error occurred.

Updates #43311
