[lldb] Make persisting result variables configurable
Context: The `expression` command uses artificial variables to store the expression
result. This result variable is unconditionally kept around after the expression command
has completed. These variables are known as persistent results. These are the variables
`$0`, `$1`, etc, that are displayed when running `p` or `expression`.
This change allows users to control whether result variables are persisted, by
introducing a `--persistent-result` flag.
This change keeps the current default behavior, persistent results are created by
default. This change gives users the ability to opt-out by re-aliasing `p`. For example:
```
command unalias p
command alias p expression --persistent-result false --
```
For consistency, this flag is also adopted by `dwim-print`. Of note, if asked,
`dwim-print` will create a persistent result even for frame variables.

[RISCV] Add performMULcombine to perform strength-reduction
The RISC-V backend thus far does not provide strength-reduction, which
causes a long (but not complete) list of 3-instruction patterns listed
to utilize the shift-and-add instruction from Zba and XTHeadBa in
strength-reduction.
This adds the logic to perform strength-reduction through the DAG
combine for ISD::MUL. Initially, we wire this up for XTheadBa only,
until this has had some time to settle and get real-world test
exposure.
The following strength-reductions strategies are currently supported:
- XTheadBa
- C = (n + 1) // th.addsl
- C = (n + 1)k // th.addsl, slli
- C = (n + 1)(m + 1) // th.addsl, th.addsl
- C = (n + 1)(m + 1)k // th.addsl, th.addsl, slli
- C = ((n + 1)m + 1) // th.addsl, th.addsl
- C = ((n + 1)m + 1)k // th.addslm th.addsl, slli
- base ISA
- C being 2 set-bits // slli, slli, add
(possibly slli, th.addsl)
Even though the slli+slli+add sequence would we supported without
XTheadBa, this currently is gated to avoid having to update a large
number of test cases (i.e., anything that has a multiplication with a
constant where only 2 bits are set) in this commit.
With the strength reduction now being performed in performMUL combine,
we drop the (now redundant) patterns from RISCVInstrInfoXTHead.td.

During discussing the approach of the patch with @ldionne, he
noticed the real reason why the test is flaky; the Apple
backdeployment targets use a dylib, which does not contain the
fix. So the test can't be tested on that platform; it only
proves the LWG issue was correct and the Standard contained

[analyzer] Remove unjustified assert from EquivalenceClass::simplify
One might think that by merging the equivalence classes (eqclasses) of
`Sym1` and `Sym2` symbols we would end up with a `State` in which the
eqclass of `Sym1` and `Sym2` should now be the same. Surprisingly, it's
not //always// true.
Such an example triggered the assertion enforcing this _unjustified_
invariant in https://github.com/llvm/llvm-project/issues/58677.
```lang=C++
unsigned a, b;
#define assert(cond) if (!(cond)) return
void f(unsigned c) {
/*(1)*/ assert(c == b);
/*(2)*/ assert((c | a) != a);
/*(3)*/ assert(a);
// a = 0 => c | 0 != 0 => c != 0 => b != 0
}
```
I believe, that this assertion hold for reasonable cases - where both
`MemberSym` and `SimplifiedMemberSym` refer to live symbols.
It can only fail if `SimplifiedMemberSym` refers to an already dead
symbol. See the reasoning at the very end.
In this context, I don't know any way of determining if a symbol is
alive/dead, so I cannot refine the assertion in that way.
So, I'm proposing to drop this unjustified assertion.
---
Let me elaborate on why I think the assertion is wrong in its current
shape.
Here is a quick reminder about equivalence classes in CSA.
We have 4 mappings:
1) `ClassMap`: map, associating `Symbols` with an `EquivalenceClass`.
2) `ClassMembers`: map, associating `EquivalenceClasses` with its
members - basically an enumeration of the `Symbols` which are known
to be equal.
3) `ConstraintRange`: map, associating `EquivalenceClasses` with the
range constraint which should hold for all the members of the
eqclass.
4) `DisequalityMap`: I'm omitting this, as it's irrelevant for our
purposes now.
Whenever we encounter/assume that two `SymbolRefs` are equal, we update
the `ClassMap` so that now both `SymbolRefs` are referring to the same
eqclass. This operation is known as `merge` or `union`.
Each eqclass is uniquely identified by the `representative` symbol, but
it could have been just a unique number or anything else - the point
is that an eqclass is identified by something unique.
Initially, all Symbols form - by itself - a trivial eqclass, as there
are no other Symbols to which it is assumed to be equal. A trivial
eqclass has //notionally// exactly one member, the representative symbol.
I'm emphasizing that //notionally// because for such cases we don't store
an entry in the `ClassMap` nor in the `ClassMembers` map, because it
could be deduced.
By `merging` two eqclasses, we essentially do what you would think it
does. An important thing to highlight is that the representative symbol
of the resulting eqclass will be the same as one of the two eqclasses.
This operation should be commutative, so that `merge(eq1,eq2)` and
`merge(eq2,eq1)` should result in the same eqclass - except for the
representative symbol, which is just a unique identifier of the class,
a name if you will. Using the representative symbol of `eq1` or `eq2`
should have no visible effect on the analysis overall.
When merging `eq1` into `eq2`, we take each of the `ClassMembers` of
`eq1` and add them to the `ClassMembers` of `eq2` while we also redirect
all the `Symbol` members of `eq1` to map to the `eq2` eqclass in the
`ClassMap`. This way all members of `eq1` will refer to the correct
eqclass. After these, `eq1` key is unreachable in the `ClassMembers`,
hence we can drop it.
---
Let's get back to the example.
Note that when I refer to symbols `a`, `b`, `c`, I'm referring to the
`SymbolRegionValue{VarRegion{.}}` - the value of that variable.
After `(1)`, we will have a constraint `c == b : [1,1]` and an eqclass
`c,b` with the `c` representative symbol.
After `(2)`, we will have an additional constraint `c|b != a : [1,1]`
with the same eqclass. We will also have disequality info about that
`c|a` is disequal to `a` - and the other way around.
However, after the full-expression, `c` will become dead. This kicks in
the garbage collection, which transforms the state into this:
- We no longer have any constraints, because only `a` is alive, for
which we don't have any constraints.
- We have a single (non-trivial) eqclass with a single element `b` and
representative symbol `c`. (Dead symbols can be representative
symbols.)
- We have the same disequality info as before.
At `(3)` within the false branch, `a` get perfectly constrained to zero.
This kicks in the simplification, so we try to substitute (simplify) the
variable in each SymExpr-tree. In our case, it means that the
`c|a != a : [1,1]` constraint gets re-evaluated as `c|0 != 0 : [1,1]`,
which is `c != 0 : [1,1]`.
Under the hood, it means that we will call `merge(c|a, c)`. where `c` is
the result of `simplifyToSVal(State, MemberSym).getAsSymbol()` inside
`EquivalenceClass::simplify()`.
Note that the result of `simplifyToSVal()` was a dead symbol. We
shouldn't have acquired an already dead symbol. AFAIK, this is the only
way we can get one at this point.
Since `c` is dead, we no longer have a mapping in `ClassMap` for it;
hence when we try to `find()` the eqclass of `c`, it will report that
it's a trivial eqclass with the representative symbol `c`.
After `merge(c|a, c)`, we will have a single (non-trivial) eqclass of
`b, c|a` with the representative symbol `c|a` - because we merged the
eqclass of `c` into the eqclass of `c|a`.
This means that `find(c|a)` will result in the eqclass with the
representative symbol `c|a`. So, we ended up having different eqclasses
for `find(c|a)` and `find(c)` after `merge(c|a, c)`, firing the
assertion.
I believe, that this assertion hold for reasonable cases - where both
`MemberSym` and `SimplifiedMemberSym` refer to live symbols.
`MemberSym` should be live in all cases here, because it is from
`ClassMembers` which is pruned in `removeDeadBindings()` so these must
be alive. In this context, I don't know any way of determining if a
symbol is alive/dead, so I cannot refine the assertion in that way.
So, I'm proposing to drop this unjustified assertion.
I'd like to thank @martong for helping me to conclude the investigation.
It was really difficult to track down.
PS: I mentioned that `merge(eq1, eq2)` should be commutative. We
actually exploit this for merging the smaller eqclass into the bigger
one within `EquivalenceClass::merge()`.
Yea, for some reason, if you swap the operands, 3 tests break (only
failures, no crashes) aside from the test which checks the state dumps.
But I believe, that is a different bug and orthogonal to this one. I
just wanted to mention that.
