RFR: jdk10: 8169646: Remove launcher's -d32/-d64 option

[Kumar Srinivasan]

Hello,

Please review the changes to remove the java launcher's data model
options  -d32/-d64, these options existed to support Solaris dual-mode
operation, however for uniformity, these options were accepted by other
platforms as well.  These options are  now obsolete, and deprecated in jdk9,
and are now being removed.

Issue: https://bugs.openjdk.java.net/browse/JDK-8169646

Thanks
Kumar

PS: Thanks to David Holmes and Igor Ignatyev the -d32/-d64 flags have been
purged from internal test suites.
