Bootstrapped and regtested on x86_64-pc-linux-gnu, OK for trunk?
Or should I include a testcase? I haven't reduced one from using the
full contents of C++23 <iostream> yet but I can do so if you prefer.

While lazy loading, instantiation of pendings can sometimes recursively
perform name lookup and begin further lazy loading. When using the
'-ftime-report' functionality this causes ICEs as we could start an
already-running timer for the importing.
This patch fixes the issue by using the 'timevar_cond*' API instead to
support such recursive calls.
PR c++/115165
gcc/cp/ChangeLog:
* module.cc (lazy_load_binding): Use 'timevar_cond*' APIs.
(lazy_load_pendings): Likewise.
