Fixes #34883
Description
EF's funcletizer (first and very important step in the query pipeline) was rewritten in EF 9, both to allow query precompilation (NativeAOT) and for better performance (see #33106). The new implementation contains a bug in the conditional expression handling when the test component of the conditional expression is client-evaluatable.
Customer impact

foo() ? x : ysometimes fail to execute.How found
Customer reported on 9.0.0-rc1
Regression
Yes, from 8.
Testing
