Mike Bayer 47f0aa47e7 Test for short term reference cycles and resolve as many as possible ...

Added test support and repaired a wide variety of unnecessary reference
cycles created for short-lived objects, mostly in the area of ORM queries.

For the 1.3 backport, includes the prefix_anon_map() optimization
from 1.4 / master which inlines the anonymous symbol generation
into a single object.   This removes a cycle from the compiler
that otherwise results in a signficantly higher number of
unreachable cycles.

Fixes: #5056
