Emit constrained atan2 intrinsic for clang builtin (#113636)
This change is part of this proposal:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294
- `Builtins.td` - Add f16 support for libm atan2 builtin
- `CGBuiltin.cpp` - Emit constraint atan2 intrinsic for clang builtin
- `clang/test/CodeGenCXX/builtin-calling-conv.cpp` - Use erff instead of
atan2 for clang builtin to lib call calling convention check, now that
atan2 maps to an intrinsic.
- add atan2 cases to llvm.experimental.constrained tests for more
backends: ARM, PowerPC, RISCV, SystemZ.
- LangRef.rst: add llvm.experimental.constrained.atan2, revise
llvm.atan2 description.
Last part of Implement the atan2 HLSL Function. Fixes #70096.

[Test] Fix usage of constrained intrinsics (#113523)
Some tests contain errors in constrained intrinsic usage, such as missed
or extra type parameters, wrong type parameters order and some other.

[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

[FPEnv][ARM] Don't call mutateStrictFPToFP when lowering
mutateStrictFPToFP can delete the node and replace it with another with the same
value which can later cause problems, and returning the result of
mutateStrictFPToFP doesn't work because SelectionDAGLegalize expects that the
returned value has the same number of results as the original. Instead handle
things by doing the mutation manually.

[ARM] Fix infinite loop when lowering STRICT_FP_EXTEND
If the target has FP64 but not FP16 then we have custom lowering for FP_EXTEND
and STRICT_FP_EXTEND with type f64. However if the extend is from f32 to f64 the
current implementation will cause in infinite loop for STRICT_FP_EXTEND due to
emitting a merge_values of the original node which after replacement becomes a
merge_values of itself.
Fix this by not doing anything for f32 to f64 extend when we have FP64, though
for STRICT_FP_EXTEND we have to do the strict-to-nonstrict mutation as that
doesn't happen automatically for opcodes with custom lowering.

[FPEnv][ARM] Add lowering of STRICT_FSETCC and STRICT_FSETCCS
These can be lowered to code sequences using CMPFP and CMPFPE which then get
selected to VCMP and VCMPE. The implementation isn't fully correct, as the chain
operand isn't handled correctly, but resolving that looks like it would involve
changes around FPSCR-handling instructions and how the FPSCR is modelled.
The fp-intrinsics test was already testing some of this but as the entire test
was being XFAILed it wasn't noticed. Un-XFAIL the test and instead leave the
cases where we aren't generating the right instruction sequences as FIXME.

[LegalizeTypes] Add SoftenFloatResult support for STRICT_SINT_TO_FP/STRICT_UINT_TO_FP
Some target like arm/riscv with soft-float will have compiling crash when using -fno-unsafe-math-optimization option.
This patch will add the missing strict FP support to SoftenFloatRes_XINT_TO_FP.

[FPEnv] Remove unnecessary rounding mode argument for constrained intrinsics
The following intrinsics currently carry a rounding mode metadata argument:
llvm.experimental.constrained.minnum
llvm.experimental.constrained.maxnum
llvm.experimental.constrained.ceil
llvm.experimental.constrained.floor
llvm.experimental.constrained.round
llvm.experimental.constrained.trunc
This is not useful since the semantics of those intrinsics do not in any way
depend on the rounding mode. In similar cases, other constrained intrinsics
do not have the rounding mode argument. Remove it here as well.
