Updated Baseline JIT OpenPOWER patches for Firefox 128ESR

I updated the Baseline JIT patches to apply against Firefox 128ESR, though if you use the Mercurial rebase extension (and you should), it will rebase automatically and only one file had to be merged — which it did for me also. Nevertheless, everything is up to date against tip again, and this patchset works fine for both Firefox and Thunderbird. I kept the fix for bug 1912623 because I think Mozilla's fix in bug 1909204 is wrong (or at least suboptimal) and this is faster on systems without working Wasm. Speaking of, I need to get back into porting rr to ppc64le so I can solve those startup crashes.

Fedora 41

Just a quick note that Fedora 41 is out, the standard Linux distro we use here on our two Raptor systems. Based on kernel 6.11, he big updates are updated packaging with DNF 5 and RPM 4.20 plus Perl 5.40, Python 3.13, LLVM 19 and gcc 14.1/glibc 2.40. Fortunately there are apparently still optional Xorg support packages for GNOME and KDE Plasma. Once the package repos have stabilized a bit, I'll have the usual minireview. For now, refresh your memory with how things went with Fedora 40, and of course Fedora 38 will be EOL in about a month based on their standard schedule.
