Enable inline stack probes on X86 with LLVM 16

The known problems with x86 inline-asm stack probes have been solved on LLVM main (16), so this flips the switch. Anyone using bleeding-edge LLVM with rustc can start testing this, as I have done locally. We'll get more direct rust-ci when LLVM 16 branches and we start our upgrade, and we can always patch or disable it then if we find new problems.

The previous attempt was rust-lang#77885, reverted in rust-lang#84708.
