The `TypeKind` repr(C) enum was missing `X86_FP80`, `FP128`, and `PPC_FP128` variants (values 4, 5, 6). When `compiler_builtins` is compiled with `--cfg f128_enabled` (new in recent nightlies), the C FFI function `LLVMRustGetTypeKind` returns 5 for fp128 types. The Rust enum had no variant for that discriminant, causing instant undefined behavior (manifesting as SIGTRAP). Also adds f16 and f128 cases to the ABI `Reg::llvm_type` float match, which previously only handled 32 and 64-bit floats.
