c7ef9c1edf Fix two type inference failures uncovered by japaric corresponding to 
UFCS form. In both cases the problems came about because we were
failing to process pending trait obligations. So change code to
process pending trait obligations before coercions to ensure maximum
type information is available (and also adjust shift to do something
similar).

Fixes #21245.

b5de8333b3 rollup merge of #21441: alexcrichton/rustc-opts 
This is a bit of cleanup work to clean out some old deprecated flags and deprecated lint names from the compiler (they've been deprecated for quite awhile now).

This also notably puts `--pretty` behind the `-Z unstable-options` flag (where it was supposed to be previously).

229243c136 rollup merge of #21418: Aatch/assume-refcount 
The reference count can never be 0, unless we're about to drop the data
completely. Using the `assume` intrinsic allows us to inform LLVM about
that invariant, meaning it can avoid unnecessary drops.

In the future, we will likely derive these `impl`s via syntax extensions or using compiler magic (see #20617). For the time being we can use these manual `impl`s.

0447721247 rollup merge of #21354: eddyb/vec-ufcs 
There are two limitations to the macro that this addresses:
1. the expected type is not propagated, coercions don't trigger
2. references inside element expressions don't outlive the `Vec`

Both of these limitations are caused by the block in the
macro expansion, previously needed to trigger a coercion
from `Box<[T; N]>` to `Box<[T]>`, now possible with UFCS.
