[Qemu-devel] [PATCH v3 26/50] target/arm: call qemu_plugin_insn_append

["Alex Bennée" <alex.bennee@linaro.org>]

From: "Emilio G. Cota" <cota@braap.org>

I considered using translator_ld* from arm_ldl_code
et al. However, note that there's a helper that also calls
arm_ldl_code, so we'd have to change that caller.

In thumb's case I'm also calling plugin_insn_append directly,
since we can't assume that all instructions are 16 bits long.
