Bootstrapped and regtested on x86_64-pc-linux-gnu, does this look OK for
trunk?

OK.

gcc/cp/ChangeLog:

        * parser.cc:
        * pt.cc:
        Use auto_timevar instead of timevar_push/pop.
        Remove wrapper functions.

Er, I named the new variables 'time' to be consistent with the existing
uses of auto_timevar in constexpr/constraint/logic.cc, but on second
thought 'tv', as used by r12-5487-g9bf69a8558638c, seems better.
So consider the names changed to 'tv':

Subject: [PATCH] c++: use auto_timevar instead of timevar_push/pop

r12-5487-g9bf69a8558638c replaced uses of timevar_cond_push/pop with
auto_cond_timevar and removed now unnecessary wrapper functions.  This
patch does the same with timevar_push/pop and auto_timevar.

        * parser.cc:
        * pt.cc:
        Use auto_timevar instead of timevar_push/pop.
        Remove wrapper functions.
