> Well... as simple wrapping of float[] into MemorySegment is not going to
work out, the Vector API does not like it due to alignment constraints (which
seems overly pedantic since it can operate fine when accessing a float[]
directly! )
But all `float[]` on the heap are just like any other heap object and
aligned to 8 bytes or something?
```
$ java -XX:+PrintFlagsFinal -version | grep -i align
bool AlignVector = false
{C2 product} {default}
intx InteriorEntryAlignment = 16
{C2 pd product} {default}
intx NumberOfLoopInstrToAlign = 4
{C2 product} {default}
int ObjectAlignmentInBytes = 8
{product lp64_product} {default}
intx OptoLoopAlignment = 16
{pd product} {default}
bool UseUnalignedLoadStores = true
{ARCH product} {default}
```
