Arthur Eubanks df5576a852 [test] Add -inject-tli-mapping to -loop-vectorize -vector-library tests
The legacy LoopVectorize has a dependency on InjectTLIMappingsLegacy.
That cannot be expressed in the new PM since they are both normal
passes. Explicitly add -inject-tli-mappings as a pass.

Follow-up to https://reviews.llvm.org/D86492.

Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher a863435128 Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

David Majnemer 12fd50410d [SLPVectorizer] Vectorizing the libm sqrt to llvm's sqrt intrinsic requires nnan
To quote the langref "Unlike sqrt in libm, however, llvm.sqrt has
undefined behavior for negative numbers other than -0.0 (which allows
for better optimization, because there is no need to worry about errno
being set). llvm.sqrt(-0.0) is defined to return -0.0 like IEEE sqrt."

This means that it's unsafe to replace sqrt with llvm.sqrt unless the
call is annotated with nnan.

Thanks to Hal Finkel for pointing this out!

David Majnemer 25d03dbcde [SLPVectorizer] Vectorize libcalls of sqrt
We didn't realize that we could transform the libcall into a vectorized
intrinsic.

Michael Zolotukhin de63aace8a Populate list of vectorizable functions for Accelerate library.
Summary:
This patch adds majority of supported by Accelerate library functions to the
list of vectorizable functions.

The full list of available vector functions could be found here:

Test Plan: Unit tests are added.

Michael Zolotukhin 6d8a2aa976 TLI: Add addVectorizableFunctionsFromVecLib.
Also, add several entries to vectorizable functions table, and
corresponding tests. The table isn't complete, it'll be populated later.
