[clang][Driver] Don't let -save-temps overwrite the input file
With -save-temps, an intermediate file named after the input can be the
input itself, e.g. the preprocessed output of a .s file on Darwin. The
driver catches this, but only checked for it when the output's name was
the input's file name. It missed two cases, and overwrote the input with
the preprocessed output:
- With -save-temps=obj, the output is in the output's directory, so
"clang -c -save-temps=obj sub/t.s -o sub/t.o" wrote "sub/t.s".
- On a case-insensitive file system, such as macOS's default, the
preprocessed output "t.s" of an input "t.S" is the same file.
Check whether the output is the same file as the input whenever temps
are saved.
Fixes #7002.

[NVPTX] Set default value of nvptx-allow-ftz-atomics to false (#231429)
This restores the strict FTZ default originally introduced in #200732 and temporarily relaxed in #206154.
Frontends can now explicitly opt in to native FTZ-mismatched atomics on a per-instruction basis using `!atomic.ignore.denormal.mode` metadata (#217585, #217586, #217587, #217588, #232725, #232726), which is supported in Clang, Flang, MLIR, and XLA. Users who need the previous behavior globally can still pass `-nvptx-allow-ftz-atomics=true`.
Update test cases to verify the new default disallow behavior.

[KnownFPClass] Combine fpext and fptrunc into a shared routine (#225188)
Implements https://github.com/llvm/llvm-project/issues/219847
Partially addresses https://github.com/llvm/llvm-project/issues/219300
Fixes:
- `DenormalMode` handling by `fptrunc`/`fpext`
- `fpext` no longer rules out `qNaN` if the input could be `sNaN`.
Changes:
- `fptrunc` now takes the input/output types.
- `fpext`/`fptrunc` take the `DenormalMode` of the source/destination
types.
I completely rewrote `fpext` and `fptrunc` to use a shared `fpconvert`
routine. Using an approach of starting from `fcAllFlags` and removing
classes instead of starting from `KnownSrc` and adding classes. This
rewrite also improves some deductions for `fptrunc`.
The internal `fpconvert` routine I added should also be able to handle

graphics/appleseed: unbreak the port's build against Python 3.13
PyEval_ThreadsInitialized() was deprecated since Python 3.9 and
had been finally removed; GIL is initialized by Py_Initialize()
since Python 3.7. We could probably drop the calls altogether,
but let's replace them with Py_IsInitialized() for extra safety.
