We generate the code in target-arm/translate.c (actually we generate
a TCG intermediate representation which is subsequently turned into
x86 instructions by the TCG backend in tcg/i386/). The main runtime
loop is in exec.c: when we call tcg_qemu_tb_exec() this is actually
a jump to generated code:
# define tcg_qemu_tb_exec(env, tb_ptr) \
    ((uintptr_t (*)(void *, void *))tcg_ctx.code_gen_prologue)(env, tb_ptr)
