[X86][LoopVectorize] Add support for arc and hyperbolic trig functions (#99383)
This change is part 2 x86 Loop Vectorization of :
https://github.com/llvm/llvm-project/pull/96222
It also has veclib call loop vectorization hence the test cases in
`llvm/test/Transforms/LoopVectorize/X86/veclib-calls.ll`
finally the last pr missed tests for
`llvm/test/CodeGen/X86/fp-strict-libcalls-msvc32.ll` and
`llvm/test/CodeGen/X86/vec-libcalls.ll` so added those aswell.
No evidence was found for arc and hyperbolic trig glibc vector math
functions
https://github.com/lattera/glibc/blob/master/sysdeps/x86/fpu/bits/math-vector.h
so no new `_ZGVbN2v_*` and `_ZGVdN4v_*` .
So no new tests in
`llvm/test/Transforms/LoopVectorize/X86/libm-vector-calls-VF2-VF8.ll`
Also no new svml and no new tests to:
`llvm/test/Transforms/LoopVectorize/X86/svml-calls.ll`
There was not enough evidence that there were svml arc and hyperbolic
trig vector implementations, Documentation was scarces so looked at test
cases in
[numpy](https://github.com/numpy/SVML/blob/32bf2a98420762a63ab418aaa0a7d6e17eb9627a/linux/avx512/svml_z0_acos_d_la.s#L8).
Someone with more experience with svml should investigate.
## Note
amd libm doesn't have a vector hyperbolic sine api hence why youi might
notice there are no tests for `sinh`.
## History
This change is part of
https://github.com/llvm/llvm-project/issues/87367's investigation on
supporting IEEE math operations as intrinsics.
Which was discussed in this RFC:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294
This change adds loop vectorization for `acos`, `asin`, `atan`, `cosh`,
`sinh`, and `tanh`.
