Update from CLang 19 to CLang 20 #137399
Description
I'm trying to build CPython with its JIT functionality.
./configure --enable-experimental-jit
make -j$(nproc)
python3.13 ./Tools/jit/build.py x86_64-pc-linux-gnu --output-dir . --pyconfig-dir . --cflags=""

JIT support for x86_64-pc-linux-gnu is still experimental!

make: *** [Makefile:3280: jit_stencils.h] Error 1
make: *** Waiting for unfinished jobs....I tried to symlink CLang 19 and CLang 19++ to their 20 counterparts and updated the ENV variables, but it still failed.
As most of us have CLang 20 and that CLang 20 is backwards-compatible with CLang 19, I feel that the files should be updated to CLang 20.
