malloc() returns a piece of uninitialized dynamic memory. We were (almost)
always able to model this behaviour. Its C++ counterpart, operator new is a
lot more complex, because it allows for initialization, the most complicated of which is the usage of constructors.
We gradually became better in modeling constructors, but for some reason, most

[analyzer] Fix assertion failure with conflicting prototype calls
It turns out we can reach the `Init.castAs<nonlock::CompoundVal>()`
expression with other kinds of SVals. Such as by `nonloc::ConcreteInt`
in this example: https://godbolt.org/z/s4fdxrcs9
```lang=C++
int buffer[10];
void b();
void top() {
b(&buffer);
}
void b(int *c) {
*c = 42; // would crash
}
```
In this example, we try to store `42` to the `Elem{buffer, 0}`.
This situation can appear if the CallExpr refers to a function
declaration without prototype. In such cases, the engine will pick the
redecl of the referred function decl which has function body, hence has
a function prototype.
This weird situation will have an interesting effect to the AST, such as
the argument at the callsite will miss a cast, which would cast the
`int (*)[10]` expression into `int *`, which means that when we evaluate
the `*c = 42` expression, we want to bind `42` to an array, causing the
crash.
Look at the AST of the callsite with and without the function prototype:
https://godbolt.org/z/Gncebcbdb
The only difference is that without the proper function prototype, we
will not have the `ImplicitCastExpr` `BitCasting` from `int (*)[10]`
to `int *` to match the expected type of the parameter declaration.
In this patch, I'm proposing to emit a cast in the mentioned edge-case,
to bind the argument value of the expected type to the parameter.
I'm only proposing this if the runtime definition has exactly the same
number of parameters as the callsite feeds it by arguments.
If that's not the case, I believe, we are better off by binding `Unknown`
to those parameters.

[FuncSpec] Compute specialisation gain even when forcing specialisation
When rewriting the call sites to call the new specialised functions, a
single call site can be matched by two different specialisations - a
"less specialised" version of the function and a "more specialised"
version of the function, e.g. for a function
void f(int x, int y)
the call like `f(1, 2)` could be matched by either
void f.1(int x /* int y == 2 */);
or
void f.2(/* int x == 1, int y == 2 */);
The `FunctionSpecialisation` pass tries to match specialisation in the
order of decreasing gain, so "more specialised" functions are
preferred to "less specialised" functions. This breaks, however, when
using the flag `-force-function-specialization`, in which case the
cost/benefit analysis is not performed and all the specialisations are
equally preferable.
This patch makes the pass calculate specialisation gain and order the
specialisations accordingly even when `-force-function-specialization`
is used, under the assumption that this flag has purely debugging
purpose and it is reasonable to ignore the extra computing effort it
incurs.

[FuncSpec] Fix specialisation based on literals
The `FunctionSpecialization` pass has support for specialising
functions, which are called with literal arguments. This functionality
is disabled by default and is enabled with the option
`-function-specialization-for-literal-constant` . There are a few
issues with the implementation, though:
* even with the default, the pass will still specialise based on
floating-point literals
* even when it's enabled, the pass will specialise only for the `i1`
type (or `i2` if all of the possible 4 values occur, or `i3` if all
of the possible 8 values occur, etc)
The reason for this is incorrect check of the lattice value of the
function formal parameter. The lattice value is `overdefined` when the
constant range of the possible arguments is the full set, and this is
the reason for the specialisation to trigger. However, if the set of
the possible arguments is not the full set, that must not prevent the
specialisation.
This patch changes the pass to NOT consider a formal parameter when
specialising a function if the lattice value for that parameter is:
* unknown or undef
* a constant
* a constant range with a single element
on the basis that specialisation is pointless for those cases.
Is also changes the criteria for picking up an actual argument to
specialise if the argument is:
* a LLVM IR constant
* has `constant` lattice value
has `constantrange` lattice value with a single element.

[lldb-vscode] Send Statistics Dump in terminated event
This patch will gather debug info & breakpoint info from the statistics dump and send to DAP in terminated event.
We will return full contents of statistics dump (`SBTarget.GetStatistics()`) as a JSON string. So that every time a new field being added, we will be able to capture them from DAP log without changing lldb-vscode.
All the info above will be append to `statistics` field in the terminated event
Test Plan
Debugged a simple hello world program from VSCode. Exit debug session in two ways: 1) run to program exit; 2) user initiated debug session end (quit debugging before program exit).
Check DAP log and see both debug sessions have statistics returned in terminated event.
Here's an example when debugging the test program:
```
{"event":"terminated","seq":0,"statistics":"{\"memory\":{\"strings\":{\"bytesTotal\":1851392,\"bytesUnused\":905933,\"bytesUsed\":945459}},\"modules\":[{\"debugInfoByteSize\":0,\"debugInfoEnabled\":false,\"debugInfoIndexLoadedFromCache\":false,\"debugInfoIndexSavedToCache\":false,\"debugInfoIndexTime\":0,\"debugInfoParseTime\":0,\"identifier\":

[LV][RISCV] Disable vectorization of epilogue loops
Epilogue loop vectorization is a feature in the vectorize intended to avoid running fully scalar code when the vector length of the main loop turns out to be either longer than the trip count of the actual loop, or with a huge remainder.
In practice, this feature appears to not have been well tuned. I honestly don't think it should be on by default at all, but it definitely shouldn't be on for RISCV. Note that other targets have also disabled it, but they've done so via disabling interleaving - which is, well, completely unrelated - and we don't want to do that for RISCV.
In the near term, many examples I'm seeing have terrible codegen for epilogue vectorization. We are greatly increasing code size for little value at reasonable VLEN values for small types. In the long term, the cases that epilogue vectorization are intended to handle are likely better handled via tail folding on RISCV.
As an aside, I also don't really trust the correctness of epilogue vectorization. The code structure is such that otherwise straight forward changes sometimes break only epilogue vectorization. The reuse of an existing vplan without careful validation opens significant room for nasty bugs. Given how rarely the code is exercised, that is not a good combination.
As such, this patch introduces a TTI hook, and completely disables epilogue vectorization on RISCV.

[clang-doc] Fix typedef/using output.
Provides an initializer for the TypedefInfo.IsUsing member. Previously
this member was uninitialized and would produce random output.
Adds the Description (code comments) to the bitcode reader/writer.
Previously the typedef/using descriptions were lost during the bitcode
round-trip. Adds a test for this.

[lld-macho] Don't sort map file entries by name

address).

Fix exception description in lldb-vscode
There is a bug in lldb-vscode that only shows stop reason ("exception") in
stopped event without showing the stop description of thrown exception. This
causes VSCode UI to only show "Paused on Exception" general message in
callstack window UI.
This patch fixes the bug so that VSCode callstack will show the detailed
exceptioni description, like "signal SIGABRT" or "EXC_BAD_ACCESS..." which
aligns with command line lldb experience.
I use C++ exception in testcase because the hardware exception description is
platform dependent and hard to verify.

[CUDA, NVPTX] Added basic __bf16 support for NVPTX.
Recent Clang changes expose _bf16 types for SSE2-enabled host compilations and
that makes those types visible furing GPU-side compilation, where it currently
fails with Sema complaining that __bf16 is not supported.
Considering that __bf16 is a storage-only type, enabling it for NVPTX if it's
enabled on the host should pose no issues, correctness-wise.
Recent NVIDIA GPUs have introduced bf16 support, so we'll likely grow better
support for __bf16 on NVPTX going forward.
