[sorry for delay, I was OOO]
I am strongly against any such change as it may lead to performance drop.
Sadly, we don't have a performance bot yet and we will simply not see a performance drop until it is too late. 

For a particular interceptor or a set of interceptors the problem can be solved by adding something like "volatile uptr x = GET_CALLER_PC();"
