Reduce QtCore lib binary size by around ~3KB, by removing template code

Reusing a template is much better then creating a new one, even if it
should inline the same code.

For some reason replacing T* by void* force gcc to remove a few bytes
per template instantiation too, it is not really significant, but it
alows us to simplify the code.

Benchmarks don't show any regressions.
