RFA: Fix possible typo in lto-cgraph.c

[Richard Sandiford]

bootstrap-asan failed on wide-int from what looks like a typo in
compute_ltrans_boundary.  The first loop uses the function-wide "node"
variable while the second loop uses a local "vnode" variable.  The problem
was that the second loop also had a reference to "node".

The patch below gets me past the boostrap failure on x86_64-linux-gnu.
OK to install?

Thanks,
Richard

        * lto-cgraph.c (compute_ltrans_boundary): Make node variables local
        to their respective blocks.  Fix inadvertent use of "node".
