ebc86b441d Fix use of has_infer_types 
* Add a new method `has_infer_types_or_consts` that's used instead most
  of the time, since there's generally no reason to only consider types.
*  Remove use of `has_closure_types`, because closures are no longer
  implicitly linked to the `InferCtxt`.

Rollup merge of #67642 - Mark-Simulacrum:relax-bounds, r=Amanieu 
Relax bounds on HashMap/HashSet

These APIs changed from the old bound listed to the new bound (possibly empty):

K: Hash + Eq -> K
* new
* with_capacity

K: Eq + Hash, S: BuildHasher -> K, S
* with_hasher
* with_capacity_and_hasher
* hasher

K: Eq + Hash + Debug -> K: Debug
S: BuildHasher -> S
HashMap as Debug

K: Eq + Hash -> K
S: BuildHasher + Default -> S: Default
HashMap as Default

Resolves #44777.

5371ddf8c6 Auto merge of #68080 - varkor:declared-here, r=petrochenkov 
Address inconsistency in using "is" with "declared here"

"is" was generally used for NLL diagnostics, but not other diagnostics. Using "is" makes the diagnostics sound more natural and readable, so it seems sensible to commit to them throughout.

dd0507c054 Make TooGeneric error in WF checking a proper error 
`TooGeneric` is encountered during WF checking when we cannot determine that a constant involving a generic parameter will always be evaluated successfully (rather than resulting in an error). In these cases, the burden of proof should be with the caller, so that we can avoid post-monomorphisation tim errors (which was the previous previous behaviour). This commit ensures that this situation produces a proper compiler error, rather than silently ignoring it or ICEing.

48859db151 Relax bounds on HashSet to match hashbrown 
No functional changes are made, and all APIs are moved to strictly less
restrictive bounds.

These APIs changed from the old bound listed to the new bound:

T: Hash + Eq -> T
* new
* with_capacity

T: Eq + Hash, S: BuildHasher -> T
* with_hasher
* with_capacity_and_hasher
* hasher

T: Eq + Hash + Debug -> T: Debug
S: BuildHasher -> S
<HashSet as Debug>

T: Eq + Hash -> T
S: BuildHasher + Default -> S: Default
<HashSet as Default>

c205f6a06a Remove mem::uninitalized from tests 
This purges uses of uninitialized where possible from test cases. Some
are merely moved over to the equally bad pattern of
MaybeUninit::uninit().assume_init() but with an annotation that this is
"the best we can do".
