1522144a - [Type checker] Don't replace function builder closures with their bodies.

[Type checker] Don't replace function builder closures with their bodies. When diagnosing failures in a function builder closure, we were unnecessarily replacing the closure expression with its body, destroying the AST and resulting in assertions due to DeclContext mismatches. Fixes SR-11350 / rdar://problem/54590425. (cherry picked from commit 187647de62fc6132c4e4c6f891edeba3133834e2)
