Fixes #38374
This is an implementation of the
addOptimizationHints
compiler flag suggested in #38374. The intent of this feature is to allow must users to receive the benefits of the/** @class */
and IIFE wrapper introduced by #32011, while being able to opt-out if needed. In our case, opting out is helpful because we have an optimization toolchain that attempts to understand and decompose classes rather than treating them as an opaque value.This is based on PR #38566 to include that bug fix.
As far as the name goes, I am not tied to
addOptimizationHints
at all, it's just an example. I am very open to changing the name, description, and default value for this compiler option. Also if I missed some places new compiler options need to be introduced or documented please point them out 😄
