Don't use periods in target names

Using a period in the target name can cause issues in e.g. cargo, see also https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Running.20tests.20on.20remote.20target

…s, r=compiler-errors

Print all features with --print target-features

This fixes `rustc --print target-features` with respect to aliases and tied features.

Before this change, the print command assumed that each LLVM feature corresponds exactly to one rustc feature.  In the case of aliases and tied features, this assumption failed and some features (such as aarch64's "pacg") were missing.  With this change, every target feature is listed.
