Improve performance of upgrade when many processes have old code
This commit utilizes the new bif erlang:check_old_code/1 to check if a
module has old code in the system or not before running
erlang:check_process_code/2. This is to optimize
release_handler:install_release (and
release_handler:check_install_release).
A new test is added which checks that after traversing all
processes/modules once and purging all old code, the second run
through this part of the code is "sufficiently" much faster.
A note is also added in the reference manual for
release_handler:install_release about how to go around the efficiency
problem of this function.
