687ee7fee4 Downgrade ProjectionTy's TraitRef to its substs 
Addresses the second part of #42171 by removing the `TraitRef` from
`ProjectionTy`, and directly storing its `Substs`.

Closes #42171.

f668999153 use field init shorthand in src/librustc 
The field init shorthand syntax was stabilized in 1.17.0 (aebd94f); we
are now free to use it in the compiler.

e1377a4f47 avoid calling mk_region unnecessarily 
this improves typeck & trans performance by 1%. This looked hotter on
callgrind than it is on a CPU.

This speeds up compilation by 3--6% across most of rustc-benchmarks.

58b75f7aa3 loosen assertion against proj in collector 
The collector was asserting a total absence of projections, but some
projections are expected, even in trans: in particular, projections
containing higher-ranked regions, which we don't currently normalize.

d37edef9dd prefer if let to match with None => {} arm in some places 
This is a spiritual succesor to #34268/8531d581, in which we replaced a
number of matches of None to the unit value with `if let` conditionals
where it was judged that this made for clearer/simpler code (as would be
recommended by Manishearth/rust-clippy's `single_match` lint). The same
rationale applies to matches of None to the empty block.

ccfb74e800 warn for where/return-types that reference regions 
This is a step towards fixing #32330. The full fix would be a breaking
change, so we begin by issuing warnings for scenarios that will break.
