RFR: 143072: [JVMCI] Port JVMCI to AArch64

[Roland Schatz]

Sorry for noticing it that late, but there seems to be no implementation 
for src/cpu/aarch64/vm/jvmciCodeInstaller_aarch64.cpp...
Of course the stuff in there could be implemented in a separate patch. 
It's rather hard to test that without an actual compiler.

Perhaps we should have a series of test analogous to the 
test/compiler/jvmci/errors tests, but for "working" instead of "broken" 
code installation. For that we would need a platform dependent "fake" 
compiler (e.g. handwritten assembly for well-known test methods).
