Trevor Gross 07fa70e104 llvm: Update reliable_f16 configuration for LLVM22 
Since yesterday, the LLVM `main` branch should have working `f16` on all
platforms that Rust supports; this will be LLVM version 22, so update
how `cfg(target_has_reliable_f16)` is set to reflect this.

Within the rust-lang organization, this currently has no effect. The
goal is to start catching problems as early as possible in external CI
that runs top-of-tree rust against top-of-tree LLVM, and once testing
for the rust-lang bump to LLVM 22 starts. Hopefully this will mean that
we can fix any problems that show up before the bump actually happens,
meaning `f16` will be about ready for stabilization at that point (with
some considerations for the GCC patch at [1] propagating).

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
