[AAPointerInfo] refactor how offsets and Access objects are tracked
AAPointerInfo now maintains a list of all Access objects that it owns, along
with the following maps:
- OffsetBins: OffsetAndSize -> { Access }
- InstTupleMap: RemoteI x LocalI -> Access
A RemoteI is any instruction that accesses memory. RemoteI is different from
LocalI if and only if LocalI is a call; then RemoteI is some instruction in the
callgraph starting from LocalI.
Motivation: When AAPointerInfo recomputes the offset for an instruction, it sets
the value to Unknown if the new offset is not the same as the old offset. The
instruction must now be moved from its current bin to the bin corresponding to
the new offset. This happens for example, when:
- A PHINode has operands that result in different offsets.
- The same remote inst is reachable from the same local inst via different paths
in the callgraph:
```
A (local inst)
|
B
/ \
C1 C2
\ /
D (remote inst)
```

[AliasAnalysis] Introduce getModRefInfoMask() as a generalization of pointsToConstantMemory().
The pointsToConstantMemory() method returns true only if the memory pointed to
by the memory location is globally invariant. However, the LLVM memory model
also has the semantic notion of *locally-invariant*: memory that is known to be
invariant for the life of the SSA value representing that pointer. The most
common example of this is a pointer argument that is marked readonly noalias,
which the Rust compiler frequently emits.
It'd be desirable for LLVM to treat locally-invariant memory the same way as
globally-invariant memory when it's safe to do so. This patch implements that,
by introducing the concept of a *ModRefInfo mask*. A ModRefInfo mask is a bound
on the Mod/Ref behavior of an instruction that writes to a memory location,
based on the knowledge that the memory is globally-constant memory (in which
case the mask is NoModRef) or locally-constant memory (in which case the mask
is Ref). ModRefInfo values for an instruction can be combined with the
ModRefInfo mask by simply using the & operator. Where appropriate, this patch
has modified uses of pointsToConstantMemory() to instead examine the mask.
The most notable optimization change I noticed with this patch is that now
redundant loads from readonly noalias pointers can be eliminated across calls,
even when the pointer is captured. Internally, before this patch,
AliasAnalysis was assigning Ref to reads from constant memory; now AA can
assign NoModRef, which is a tighter bound.

instructions due to the need for v32i1 or v64i1.
I wanted to enable 128-bit intrinsics with avx512vl, but the
__builtin_ia32_selectb_128 used in the header file requires avx512bw.
The codegen test for the same is also not using a masked instruction
because vselect with v16i1 mask and v16i8 is not legal so is expanded
before isel. To fix these issues we need a mask specific builtin and a
mask specific ISD opcode.
Fixes PR58687.

[flang][NFC] move constant lowering into its own unit
This patch moves intrinsic evaluate::Constant<T> lowering into its own
unit outside of ScalarExpr and genarr lowering so that it can
be used by the new lowering without any changes.
DerivedType lowering cannot be shared at that stage because it is too
correlated with the current lowering (requires structure constructor
and designator lowering).
The code had to be refactored quite a bit so that it could be carved
out, but the only "functional" change is that the length of character
arrays lowered by genarr is now `index` instead of `i64` (see test change).
One non-functional benefit of the change is that `toEvExpr` is not
needed anymore and some compile time copies of big constant arrays
that it was causing are removed (see old calls in previous genarr code),
although I am not sure any compile time speed-ups are visible here.

[BasicBlockUtils] Add a new way for CreateControlFlowHub()
The existing way of creating the predicate in the guard blocks uses
a boolean value per outgoing block. This increases the number of live
booleans as the number of outgoing blocks increases. The new way added
in this change is to store one integer to represent the outgoing block
we want to branch to, then at each guard block, an integer equality
check is performed to decide which a specific outgoing block is taken.
Using an integer reduces the number of live values and decreases
register pressure especially in cases where there are a large number
of outgoing blocks. The integer based approach is used when the
number of outgoing blocks crosses a threshold, which is currently set
to 32.

[lldb][CPlusPlus] Implement CPlusPlusLanguage::GetFunctionDisplayName
This patch implements the `GetFunctionDisplayName` API which gets
used by the frame-formatting code to decide how to print a
function name.
Currently this API trivially returns `false`, so we try to parse
the demangled function base-name by hand. We try find the closing
parenthesis by doing a forward scan through the demangled name. However,
for arguments that contain parenthesis (e.g., function pointers)
this would leave garbage in the frame function name.
By re-using the `CPlusPlusLanguage` parser for this we offload the
need to parse function names to a component that knows how to do this
already.
We leave the existing parsing code in `FormatEntity` since it's used
in cases where a language-plugin is not available (and is not
necessarily C++ specific).
**Example**
For following function:
```
int foo(std::function<int(void)> const& func) { return 1; }
```
Before patch:
```
frame #0: 0x000000010000151c a.out`foo(func= Function = bar() )> const&) at sample.cpp:11:49
