Cycles: Revert changes to inline flags enabled for release only

It appears it's not really needed for convenient debugging when
using proper flags passed to the compiler. Basically, it is -g3
and set breakpoint to a function as if it's not in the namespace.

Not as if a code was any wrong, just it's possible to have more
clear solution for the issue i've tried to solve in the past.
