For UNSPEC part, we can create a new define_insn with genenral operation and
accept both gpr and mask alternatives just like other logic patterns.
For gpr version, we can split it to xor + not after reload.

Build with -O2 demonstrates the same valgrind problem, so someone this week,
between the two git hashes mentioned, has broken the -O2 build.
I haven't got the compute power here to do the bisect. Advice

I can tell you that last weekend's valgrind build with -O2 went fine.
That was from git hash ca01d2526917ec6e.
This weekend's valgrind build, with -O3 enabled, is from git hash

It worked with:
gcc version 13.0.0 20221008 (experimental)
(Compiler-Explorer-Build-gcc-705ed42a1ad950860f46c51216ff69dbe0f4857a-binutils-2.38)
So definitely a recent regression.

llvm/lib/Target/RISCV/RISCVISelLowering.cpp is huge source and it might have
undefined code in it.
Maybe narrow down which function is going wrong.
Maybe fire up gdb and see where the infinite loop is
