8185505: AArch64: Port AOT

[Ningsheng Jian]

Hi Andrew,

This is great! Some minor comments:

I can see both the jdk patch and Graal PR contain changes of AArch64Assembler.java and AArch64MacroAssembler.java, but the changes looks somewhat different. How will they be synced?

I noticed that in make/hotspot/lib/JvmFeatures.gmk line ~144, there's:

  JVM_EXCLUDE_FILES += \
      compiledIC_aot_x86_64.cpp

Do you want to add compiledIC_aot_aarch64.cpp to that list?

I also found that _immutable_PIC and its getters/setters are in the INCLUDE_AOT block, but some of their uses are not:

src/hotspot/cpu/aarch64/compiledIC_aarch64.cpp:

61   if (cbuf.immutable_PIC()) {

src/hotspot/share/jvmci/jvmciCodeInstaller.cpp:

594   buffer.set_immutable_PIC(_immutable_pic_compilation);
628   buffer.set_immutable_PIC(_immutable_pic_compilation);

Thanks,
Ningsheng
