Hi!
I'd like to backport this changeset to prevent a crash when AsyncProfiler is used on Mac M1.
The backport is not clean:
1. RISCV is not part of jdk17
2. mallocTracker.cpp is not updated since 8281023 was not backported to jdk17
3. vmError_posix.cpp requires manual update due to 8289350 is missed at jdk19+
4. Need to add globals.hpp to fix builds without precompiled headers
There is follow up for this case:
1. 8284997: arm32 build crashes since JDK-8283326
2. 8288719: [arm32] SafeFetch32 thumb interleaving causes random crashes
