when the transparency mode is `.all`, then one expects `getFunInfo` and
`inferType` to also work with that transparency mode.

While `initialize` pretended it had the declaration name of the constant
to be initialized, missing declaration ranges for the latter led call
hierarchy etc. to ignore the definition
Lake no longer attempts to fetch the Reservoir build cache if the build
directory is already present. Plus, failure of the automatic fetch now
only produces a trace message, not a warning.
@kim-em, I'm happy to keep any subset of `foldl_min`, `foldl_min_right`,
`foldl_min_le`, `foldl_min_min_of_le` (should that one have been called
`foldl_min_le_of_le`?). Which ones do you like?
I think the overhead (runtime/later proving) of using `for` is paid off
by being able to short-circuit.
These functions are needed downstream to switch over the Std.HashSet.
On Windows, shared libraries must be removed before linking. Otherwise,
linking can fail with "Permission denied" when the libraries are in use.
This ensures such removal is done for the new `libLake_shared.dll` and
both parts of `libleanshared`.
Lake no longer attempts to fetch Reservoir build caches (barrels) for
non-Reservoir dependencies, and it will only fetch them for Reservoir
dependencies in the presence of a known toolchain.
Also, optional build job failures are now only displayed in verbose
mode.
In C, these are supported only as a vendor extension; they should
instead use proper C99 flexible array members.
In C++, both `[]` and `[0]` are vendor extensions.

The constructor `AttributeExtensionOLeanEntry.decl` and related code
seems to be unused, and has been unused since its introduction in
a77598f7cf three years ago. Probably worth
removing (and changing the now one-constructor inductive into a
structure).
ac_nf is a counterpart to ac_rfl, which normalizes bitvector expressions
with respect to associativity and commutativity.
While there, also add test coverage for ac_rfl and ac_nf for BitVec,
complementing the existing test coverage.
The lemma `exists_const` already handles all real cases of `(∃ _ : α, p)
↔ p` for general types `α`. If there are no `Nonempty` instances and
this lemma cannot apply, it seems unlikely that simp could make more
progress with `(∃ _ : α, p) ↔ Nonempty α ∧ p`.
However, it is still worth simplifying `(∃ _ : p, q)` to `p ∧ q`.
Also adds a `Nonempty (Decidable a)` instance, which is used by Mathlib.

... and mark `getElem_setWidth` as `@[simp]`.
`getElem_rotateLeft` and `getElem_rotateRight` have a non-trivial rhs
but we follow `getLsbD_[rotateLeft|rotateRight]`for consistency.

Adds Reservoir as another possible source of build caches in addition to
GitHub releases. If a GitHub release is not configured for a Reservoir
dependency, it will attempt download a build cache from Reservoir. Like
with GitHub releases, failure will not stop the build and instead issue
a warning. Many of the Lake API calls related to these build caches were
refactored and renamed, with the old names remaining around as
deprecated aliases.
Build cache downloads (from Reservoir or GitHub) can now be disabled via
the `--no-cache` CLI option or the `LAKE_NO_CACHE` environment variable.
A disabled cache can be re-enable with the `--try-cache` CLI option.
Macros sometimes create auxiliary types and instances about them, and
they rely on the instance name generate to create unique names in that
case.
This modifies the automatic name generator to add a fresh macro scope to
the generated name if any of the constants in the type of the instance
themselves have macro scopes.
Closes#2044
Generally works best to pick up the proofs by unification with the lhs.
pinging @hargoniX as this goes by, as it changes some proofs in
bv_decide (nothing interesting, just a bit simpler)
