Hi Matt,

Translation logic may partially decode an instruction, then abort and
remove the instruction from the TB. This can happen for example when an
instruction spans two pages. In this case, plugins may get an incorrect
result when calling qemu_plugin_tb_n_insns to query for the number of
instructions in the TB. This patch updates plugin_gen_tb_end to set the
final instruction count.

num_insns is a 'size_t'.
