RFR: 8375498: [VectorAPI] Dump primary vector IR details with -XX:+TraceNewVectors

[Jatin Bhateja]

Patch to add support for dumping primary vector IR created by various VectorAPI inline expanders.
Currently auto-vectorization prints the newly create vector IR with -XX:+TraceNewVectors, similar message is
now emitted for VectorAPI.
 

TraceNewVectors [AutoVectorization]: 1397 AddVI === _ 1395 1396 [[ ]] #vectorx<I,4>

TraceNewVectors [VectorAPI]: 1591 AddVI === _ 1545 1569 [[ ]] #vectory<I,8> !jvms: IntVector::lanewiseTemplate @ bci:154 (line 798) Int256Vector::lanewise @ bci:3 (line 278) Int256Vector::lanewise @ bci:3 (line 43) IntVector::add @ bci:5 (line 1380) AddTestI::workload @ bci:34 (line 18)


Thanks,
Jatin
