SCQIndexing reduce method size for inlining

[tgd]

In SCQIndexing the methods linearScanByPosition0 and setPositionForSequenceNumber are too large to be inlined with default JVM inlining configuration. The output of JitWatch jarScan is shown below. The last number on each line is the method length - we need to reduce to sub 325.

./jarScan.sh --mode=maxMethodSize --limit=325 ~/m2link/repository/net/openhft/chronicle-queue/5.24ea25-SNAPSHOT/chronicle-queue-5.24ea25-SNAPSHOT.jar | grep SCQ

"net.openhft.chronicle.queue.impl.single","SCQIndexing","linearScanByPosition0","net.openhft.chronicle.wire.Wire,long,long,long,boolean",430
"net.openhft.chronicle.queue.impl.single","SCQIndexing","setPositionForSequenceNumber","net.openhft.chronicle.queue.impl.ExcerptContext,long,long",338

In the linked pull request both methods were refactored to bring them down to a shorter size meaning they will now be within the limit to be inlined.
