RFR: 8296163: [aarch64] Cleanup Pre/Post addressing mode classes

Tue Nov 1 10:28:38 UTC 2022

Please review this cleanup of the aarch64 Pre, Post, and PrePost addressing
mode helper classes.

The special functions for the PrePost class are changed from public to
protected, to ensure no slicing is possible.

In the Post class constructors, initialization of the members declared
directly in that class is now performed in the ctor-initializer rather than by
assignments in the body.

The member reader functions in PrePost and Post are now const.
