("[PATCH v2 00/21] Rewrite plugin code generation")

This is an attempt to fix
https://gitlab.com/qemu-project/qemu/-/issues/2208
("PC is not updated for each instruction in TCG plugins")

I have only updated target/i386 so far, but basically all targets
need updating for the new callbacks.  Extra points to anyone who
sees how to avoid the extra code duplication.  :-)
