[REDO] JDK-8285802 AArch64: Consistently handle offsets in MacroAssembler as 64-bit quantities

The following tests are failing in the JDK19 CI in Tier1:

tools/doclint/tool/StatsTest.java
jdk/javadoc/tool/8224612/OptionsTest.java
jdk/javadoc/doclet/testDocletExample/TestDocletExample.java

Here's hs_err_pid snippets from the OptionsTest.java failure:

# Internal Error (assembler_aarch64.hpp:251), pid=3232143, tid=3232158
