perf metric: Move runtime value to the expr context

Browse Source 
The runtime value is needed when recursively parsing metrics, currently
a value of 1 is passed which is incorrect.

Rather than add more arguments to the bison parser, add runtime to the
context.

Fix call sites not to pass a value. The runtime value is defaulted to 0,
which is arbitrary. In some places this replaces a value of 1, which was
also arbitrary.

This shouldn't affect anything other than PPC.

The use of 0 or 1 shouldn't matter as a proper runtime value would be
needed in a case that it did matter.
