target-arm: A64: add stubs for a64 specific helpers We will need helpers that only make sense with AArch64. Add helper-a64.{c,h} files as stubs that we can fill with these helpers in the following patches.

target/arm: Split helper_msr_i_pstate into 3 The EL0+UMA check is unique to DAIF. While SPSel had avoided the check by nature of already checking EL >= 1, the other post v8.0 extensions to MSR (imm) allow EL0 and do not require UMA. Avoid the unconditional write to pc and use raise_exception_ra to unwind.

target-arm: emulate aarch64's LL/SC using cmpxchg helpers Emulating LL/SC with cmpxchg is not correct, since it can suffer from the ABA problem. Portable parallel code, however, is written assuming only cmpxchg--and not LL/SC--is available. This means that in practice emulating LL/SC with cmpxchg is a viable alternative. The appended emulates LL/SC pairs in aarch64 with cmpxchg helpers. This works in both user and system mode. In usermode, it avoids pausing all other CPUs to perform the LL/SC pair. The subsequent performance and scalability improvement is significant, as the plots below show. They plot the throughput of atomic_add-bench compiled for ARM and executed on a 64-core x86 machine.

arm/translate-a64: add FP16 x2 ops for simd_indexed A bunch of the vectorised bitwise operations just operate on larger chunks at a time. We can do the same for the new half-precision operations by introducing some TWOHALFOP helpers which work on each half of a pair of half-precision operations at once. Hopefully all this hoop jumping will get simpler once we have generically vectorised helpers here.
