## What changes are proposed in this pull request?
This commit introduces support for the Scalable Vector Extension (SVE) in
SparkFloorFunction.
## How was this patch tested?
We've used Google's microbenchmark `BM_SparkFloorFunction_For_Float64` to
test the patch. The results are presented below.
```
./build_gcc/utils/extern-local-engine/tests/benchmark_local_engine
--benchmark_filter="BM.*SparkFloor.*Float64"
# Before optimization (Scalar)
----------------------------------------------------------------------------
Benchmark Time CPU Iterations
----------------------------------------------------------------------------
BM_SparkFloorFunction_For_Float64 79407 ns 79407 ns 8768
# After optimization (SVE)
----------------------------------------------------------------------------
Benchmark Time CPU Iterations
----------------------------------------------------------------------------
BM_SparkFloorFunction_For_Float64 40479 ns 40479 ns 17291
```
We are getting around 2x performance improvement on AWS Graviton3
(m7g.4xlarge).
## Note
SVE detection and macros used here are enabled in Clickhouse. We are raising
this PR as draft since the Clickhouse PR is under review. Here in the
Clickhouse PR for reference -
