RFR: 8350303: ARM32: StubCodeGenerator::verify_stub(StubGenStubId) failed after JDK-8343767

[Hao Sun]

We encountered the following runtime error on ARM32:


assert(StubRoutines::stub_to_blob(stub_id) == blob_id()) failed: wrong blob initial for generation of stub atomic_add


I suppose it might be a mistake in JDK-8343767. `atomic_add` stub belongs to **initial** stubs, but it is set as **compiler** stub in JDK-8343767.

Note that only ARM32 is affected as only ARM32 defines this stub.

Tests: cross-build for `arm32, ppc64, riscv64, s390x` passed. Tier1~3 passed on Linux/AArch64 and Linux/x86_64
