[RISCV] Pre-commit RVV instructions to the Ands45 scheduling model and tests (#171954)

This is like what spacemit x60 did in

[RISCV] Mark the Xqci Qualcomm uC Vendor Extension as non-experimental (#173331)

Version 0.13 of the Xqci Qualcomm uC Vendor Extension has been marked as
frozen. We've had assembler support for this since LLVM20 and code
generation support since LLVM21. I think we have enough coverage in the
code base to mark the extension as non-experimental.

[lldb] Add Python 3.8 compatibility for lldbtest.py (#173392)

follow up from 9892870687e0af00e798474aa5cecfd4647071e1 as we recently
added type hints to this file

[lld][WebAssembly] Don't export deps for unused stub symbols (#173422)

When a stub .so file contains
```
A: B
```

And `A` is defined in bitcode that's pulled in for LTO, but both `A` and
`B` are removed in `LTO::linkRegularLTO` due to not being dead:
https://github.com/llvm/llvm-project/blob/24297bea9672722d8fbaaff137b301b0becaae9c/llvm/lib/LTO/LTO.cpp#L1042-L1054
Then the symbol `A` becomes undefined after LTO, `processStubLibraries`
tries to import `A` from JS, and tries to export its dependency `B`:
https://github.com/llvm/llvm-project/blob/24297bea9672722d8fbaaff137b301b0becaae9c/lld/wasm/Driver.cpp#L1108-L1109
But `B` is gone, causing this error:
```console
wasm-ld: error: ....: undefined symbol: B. Required by A
```

This PR checks if the symbol is used in regular objects before trying to
exporrt its dependences, ensuring the case above doesn't crash the
linker.

[flang] improve compatibility with mingw headers (#172041)

The mingw headers declare `__environ` already, leading to warnings due
to missing dllimport here. Similarly with _WIN32_WINNT may be already
defined from a header leading to nuisance warnings. And the getpid is
not defined in the current header set (it is in process.h), so that
needs to be defined, just like MSVC (this replaces
