RFR: 8255298: Remove SurvivorAlignmentInBytes functionality

[Thomas Schatzl]

Hi all,

  can I have reviews to remove the SurvivorAlignmentInBytes functionality? It has not been in use for a long time if ever, and can be removed. Searching the web also indicates that apart from the usual lists of all options and CRs it is never mentioned.

SurvivorAlignmentInBytes is an experimental option so no further process is required.

Testing: tier1-5

Thanks,
  Thomas
