Allow use of [_ ; n] syntax for fixed length and repeating arrays.

This does NOT break any existing programs because the `[_, ..n]` syntax is also supported.

parse_ty() no longer takes a boolean parameter. quote_ty! implementation has not yet been modified accordingly.
As a matter of fact, quote_ty! was not covered by tests. One test (called qquotes) references it, but it has been ignored for nearly one year and now need heavy refactoring.
quote_token.rs seemed like a good place to test quote_ty!, many other quote_*! macros were asserted there.

auto merge of #19884 : nikomatsakis/rust/issue-19730-perfect-forwarding, r=pnkfelix
...
Rewrite how the HRTB algorithm matches impls against obligations. Instead of impls providing higher-ranked trait-references, impls now once again only have early-bound regions. The skolemization checks are thus moved out into trait matching itself. This allows to implement "perfect forwarding" impls like those described in #19730 . This PR builds on a previous PR that was already reviewed by @pnkfelix.

Centralize on using Binder to introduce new binding levels, rather than having FnSig carry an implicit binding level. This means that we be more typesafe in general, since things that instantiate bound regions can drop the Binder to reflect that.

Rename the code that replaces unbound variables to "freshen" rather than "skolemize" -- strictly speaking, this is not skolemization, because it is not discharging quantifiers. Also, the trait selection code will still be doing true skolemization, so it would be a confusing overlap of names.

Fix a bug in the opt-in-copy work: it was failing to liberate the regions bound in the impl before searching for Copy implements for all fields, leading to problems in the "copyability check". Basically the copyability check would wind up looking for an impl of for<'tcx> Foo<&'tcx T>. The impl that exists however is impl<T> Copy for Foo<T> and the current rules do not consider that a match (something I would like to revise in a later PR).
