[clang] Reland Add tanf16 builtin and support for tan constrained intrinsic (#94559)
Relanding this PR now that
https://github.com/llvm/llvm-project/pull/90503 has merged. with `FTAN`
landing in
[TargetLoweringBase.cpp:L1021](https://github.com/llvm/llvm-project/blob/main/llvm/lib/CodeGen/TargetLoweringBase.cpp#L1020C23-L1021C63
) There is now a llvm tan intrinsic 32\64\128 Expand case for all llvm
backends.
In LLVM, the `llvm.experimental.constrained.cos` and
`llvm.experimental.constrained.sin` intrinsics are used for performing
cosine and sine calculations with additional constraints on
floating-point operations. This behavior is expected for all
floating-point math intrinsics. This change adds these constraints for
the `tan` intrinsic.
- `Builtins.td` - replace TanF128 with F16F128MathTemplate
- `CGBuiltin.cpp` - map existing tan builtins to `tan` and
`constrained_tan` intrinsic
- `ConstrainedOps.def` map tan and constrained_tan to an ISDOpcode.
resolves #91421
