[libc++][Modules] Remove explicit exports from modules that `export *`
This may be a clang bug, but explicit exports interfere with `export *`, especially in local submodule visibility mode. For example, exporting `depr.stdint_h` from `cstdint` causes std::int32_t to become an "unresolved using declaration" in LSV if `cstdint` and `stdint.h` are promoted to top level modules. This was previously worked around by exporting `Darwin.C.stdint` in `depr.stdint_h`, but that only works on Apple platforms, and it stops working when `cstdint` and `stdint.h` are promoted to top level modules.
Remove all of the explicit `export` statements in modules that have `export *`.

This violates our definition of type-consistency that the pass is supposed to enforce and also prevents SROA and mem2reg from eliminating `alloca`s.
This patch fixes that by splitting these stores into multiple stores.
It does so by simply using logical shift rights and truncating the produced value to the size of the field, optionally bitcasting before storing into the field.

[dataflow] Replace most BoolValue subclasses with references to Formula (and AtomicBoolValue => Atom and BoolValue => Formula where appropriate)
This properly frees the Value hierarchy from managing boolean formulas.
We still distinguish AtomicBoolValue; this type is used in client code.
However we expect to convert such uses to BoolValue (where the
distinction is not needed) or Atom (where atomic identity is intended),
and then fold AtomicBoolValue into FormulaBoolValue.
We also distinguish TopBoolValue; this has distinct rules for
widen/join/equivalence, and top-ness is not represented in Formula.
It'd be nice to find a cleaner representation (e.g. the absence of a
formula), but no immediate plans.
For now, BoolValues with the same Formula are deduplicated. This doesn't
seem desirable, as Values are mutable by their creators (properties).
We can probably drop this for FormulaBoolValue immediately (not in this
patch, to isolate changes). For AtomicBoolValue we first need to update
clients to stop using value pointers for atom identity.
The data structures around flow conditions are updated:
- flow condition tokens are Atom, rather than AtomicBoolValue*
- conditions are Formula, rather than BoolValue
Most APIs were changed directly, some with many clients had a
new version added and the existing one deprecated.
The factories for BoolValues in Environment keep their existing
signatures for now (e.g. makeOr(BoolValue, BoolValue) => BoolValue)
and are not deprecated. These have very many clients and finding the
most ergonomic API & migration path still needs some thought.

[ValueTracking] Don't handle ptrtoint with mismatches sizes
When processing assumes, we also handle assumes on ptrtoint of the
value. In canonical IR, these will have the same size as the value.
However, in non-canonical IR there may be an implicit zext or
trunc, which results in a bit width mismatch. We currently handle
this by adjusting bitwidth everywhere, but this is fragile and I'm
pretty sure that the way we do this is incorrect for some predicates,
because we effectively end up commuting an ext/trunc and an icmp.
Instead, add an m_PtrToIntSameSize() matcher that will only handle
bitwidth preserving cases. For the bitwidth-changing cases, wait
until they have been canonicalized.
The original handling for this was added purely to prevent crashes
in an earlier implementation which failed to account for this
entirely.

[clangd][c++20] Drop first template argument in code completion in some contexts.
In case of a top level context the first template argument of a concept
should be dropped. Currently the indexer doesn't support different
signatures for different contexts (for an index entry always the default
`Symbol` context is used). Thus we add a hack which checks if we are in
a top level context and have a concept and in that case removes the
first argment of the signature and snippet suffix. If there is only a
single argument, the signature and snippet suffix are completly
removed. The check for the first argument is done by simply looking for
the first comma which should be sufficient in most cases.
Additionally extend test environment to support adding artificial index
entries with signature and completion snippet suffix.

[X86] Remove CPU_SPECIFIC* MACROs and add getCPUDispatchMangling
This refactor patch means to remove CPU_SPECIFIC* MACROs in X86TargetParser.def
and move those information into ProcInfo of X86TargetParser.cpp. Since these
two files both maintain a table with redundant info such as cpuname and its
features supported. CPU_SPECIFIC* MACROs define some different information. This
patch dealt with them in these ways when moving:
1.mangling
This is now moved to Mangling in ProcInfo and directly initialized at array of
Processors. CPUs don't support cpu_dispatch/specific are assigned '\0' as
mangling.
2.CPU alias
The alias cpu will also be initialized in array of Processors, its attributes
will be same as its alias target cpu. Same feature list, same mangling.
3.TUNE_NAME
Before my change, some cpu names support cpu_dispatch/specific are not
supported in X86.td, which means optimizer/backend doesn't recognize them. So
they use a different TUNE_NAME to generate in IR. In this patch, I added these
missing cpu support at X86.td by utilizing existing Features and XXXTunings, so
that each cpu name can directly use its own name as TUNE_NAME to be supported
by optimizer/backend.
4.Feature list
The feature list of one CPU maintained in X86TargetParser.def is not same as
the one in X86TargetParser.cpp. It only maintains part of features of one CPU
(features defined by X86_FEATURE_COMPAT). While X86TargetParser.cpp maintains
a complete one. This patch abandons the feature list maintained by CPU_SPECIFIC*
MACROs because assigning a CPU with a complete one doesn't affect the
functionality of cpu_dispatch/specific.
Except these four info, since some of CPUs supported by cpu_dispatch/specific
doesn's support clang options like -march, -mtune before, this patch also kept
this behavior still by adding another member OnlyForCPUDispatchSpecific in
ProcInfo.

[LoopUnroll] Fold add chains during unrolling
Loop unrolling tends to produce chains of
`%x1 = add %x0, 1; %x2 = add %x1, 1; ...` with one add per unrolled
iteration. This patch simplifies these adds to `%xN = add %x0, N`
directly during unrolling, rather than waiting for InstCombine to do so.
The motivation for this is that having a single add (rather than
an add chain) on the induction variable makes it a simple recurrence,
which we specially recognize in a number of places. This allows
InstCombine to directly perform folds with that knowledge, instead
of first folding the add chains, and then doing other folds in another
InstCombine iteration.
Due to the reduced number of InstCombine iterations, this also
results in a small compile-time improvement.

[analyzer] Differentiate lifetime extended temporaries
This patch introduces a new `CXXLifetimeExtendedObjectRegion` as a representation
of the memory for the temporary object that is lifetime extended by the reference
to which they are bound.
This separation provides an ability to detect the use of dangling pointers
(either binding or dereference) in a robust manner.
For example, the `ref` is conditionally dangling in the following example:
```
template<typename T>
T const& select(bool cond, T const& t, T const& u) { return cond ? t : u; }
int const& le = Composite{}.x;
auto&& ref = select(cond, le, 10);
```
Before the change, regardless of the value of `cond`, the `select()` call would
have returned a `temp_object` region.
With the proposed change we would produce a (non-dangling) `lifetime_extended_object`
region with lifetime bound to `le` or a `temp_object` region for the dangling case.
We believe that such separation is desired, as such lifetime extended temporaries
are closer to the variables. For example, they may have a static storage duration
(this patch removes a static temporary region, which was an abomination).
We also think that alternative approaches are not viable.
While for some cases it may be possible to determine if the region is lifetime
extended by searching the parents of the initializer expr, this quickly becomes
complex in the presence of the conditions operators like this one:
```
Composite cc;
// Ternary produces prvalue 'int' which is extended, as branches differ in value category
auto&& x = cond ? Composite{}.x : cc.x;
// Ternary produces xvalue, and extends the Composite object
auto&& y = cond ? Composite{}.x : std::move(cc).x;
```
Finally, the lifetime of the `CXXLifetimeExtendedObjectRegion` is tied to the lifetime of
the corresponding variables, however, the "liveness" (or reachability) of the extending
variable does not imply the reachability of all symbols in the region.
In conclusion `CXXLifetimeExtendedObjectRegion`, in contrast to `VarRegions`, does not
need any special handling in `SymReaper`.
