[clang][bytecode] Fix crash caused by overflow of Casting float number to integer (#177815)
Before this PR evaluation process will stop immediately regradless of
whether it's set to handle overflow,
this will prevent us getting value from stack, which leads to crash(with
or without assertion).
Closes #177751.
[clang][bytecode] Fix crash on discarded complex comparison (#177731)
Fixes llvm#176902: [clang][bytecode] crashes on ill-formed
_Static_assert comparing complex value
This patch resolves a crash in Clang's constant evaluation when handling
complex number comparisons in discarded expressions, such as those
involving short-circuiting logical operators. The crash occurred due to
unnecessary evaluation of the comparison in the experimental constant
interpreter.
The issue was originally observed and minimized in the following
example:
```cpp
#define EVAL(a, b) _Static_assert(a == b, "")
void foo() {
EVAL(; + 0, 1i);

archivers/py-zopfli: disable Python limited API
Upstream uses the limited API to allow generating a wheel compatible
with all currently supported CPython versions regardless of which
version is actually used to generate it, but this is not needed
here. Disabling also allows building on 3.13t.

[C++20] [Modules] Set ManglingContextDecl when we need to mangle a lambda but it's nullptr (#177899)
Close https://github.com/llvm/llvm-project/issues/177385
The root cause of the problem is, when we decide to mangle a lamdba in a
module interface while the ManglingContextDecl is nullptr, we didn't
update ManglingContextDecl. So that the following use of
ManglingContextDecl is an invalid value.
[RISC-V][MC] Introduce RVY extension feature
This adds the initial feature for the base RVY extension,
other extensions such as the hybrid mode will be added later.

[RISC-V] Reduce code duplication for uimm*_lsb* operands. NFC
Use a common tablegen class instead of duplicating all the data and add a
new case macro to handle the isShiftedUInt<>() call. This refactoring was
motivated by adding RVY support since I needed to add uimm{9,10}_lsb0000.
Pull Request: https://github.com/llvm/llvm-project/pull/177743
Clean up this test a bit.
1. Use printf instead of echo
2. Use $( ) instead of ``
3. Check exit status of commands being tested
4. Misc other stuff (use -ne rather than != when comparing numbers, ...)
[RISCV] Use inheritance to simplify RVInstSet*VL* classes. NFC (#177797)
Rename classes to start with RVInstV to make it more clear they are
vector related.
Remove VirtualBox service automation from `setup_virtualbox`
- Removed calls to `enable_rc_conf` and `start_service_safe` for `vboxguest` and `vboxservice` within `setup_virtualbox`.
Not supported with Xlibre at this moment.
