Optimize cmMakefile::ExpandVariablesInStringNew.
We can remove the temporary allocations required for the
default-constructed t_lookup passed into the openstack by refactoring
the code slightly. Furthermore, we use a vector instead of a stack,
since the latter is based on a deque which is not required for a
heap / lifo structure.
This patch removes ~215k allocations.
This hotspot was found with heaptrack.
