Hi,
instrumentation thunks are de-facto transparent aliases and thus their bodies
should not be streamed (longer term plan is to reorganize them to aliases).
This avoids an ICE when mixing instrumented and non-instrumented files in LTO.
Bootstrapped/regtested x86_64-linux, plan to commit it if there are no
complains.
