lto: Stream has_unroll flag during LTO [PR116140]
When #pragma GCC unroll is processed in
tree-cfg.cc:replace_loop_annotate_in_block, we set both the loop->unroll
field (which is currently streamed out and back in during LTO) but also
the cfun->has_unroll flag.
cfun->has_unroll, however, is not currently streamed during LTO. This
patch fixes that.
Prior to this patch, loops marked with #pragma GCC unroll that would be
unrolled by RTL loop2_unroll in a non-LTO compilation didn't get
unrolled under LTO.
