tcg: Optimize fence instructions
This commit optimizes fence instructions. Two optimizations are currently implemented: (1) unnecessary duplicate fence instructions, and (2) merging weaker fences into a stronger fence. [rth: Merge tcg_optimize_mb back into tcg_optimize, so that we only loop over the opcode stream once. Merge "unrelated" weaker barriers into one stronger barrier.] Signed-off-by: Pranith Kumar <bobby.prani@gmail.com> Message-Id: <20160823134825.32578-1-bobby.prani@gmail.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
