Hey @farzonl ,

Unfortunately I cannot have a strong opinion on Global ISel contributions.

#### Regarding sources I've modified in the past
The below look OK to me:
- additions to `VecFuncs.def`
- all `replace-with-veclib-*`
- LoopVectorize `veclib-intrinsic-calls.ll`

I verified the existence of the symbols used in sources and test files on ArmPL and SLEEF libraries (see list at the bottom).

---

#### Regarding the rest of the sources and tests:
They also look reasonable and similar to existing sources, but I cannot vouch for them.

BTW in `GlobalISel/arm64-irtranslator.ll` other functions have variants for double as well for scalable vectors (float and double). Why this isn't the case for the newly added functions as well?
