target/sh4: fetch code with translator_ld

Browse Source 
There is a small wrinkle with the gUSA instruction. The translator
effectively treats a (known) gUSA sequence as a single instruction.
For the purposes of the plugin we end up with a long multi-instruction
qemu_plugin_insn.

If the known sequence isn't detected we shall never run this
translation anyway.
