`PreCheckFunctionBuilderRequest` applies `PreCheckExpression` to the expressions inside the function body. Previously it used to receive only `AnyFunctionRef` (`FunctionDecl` or `ClosureExpr`) as the parameter. However, when fast-completion kicks-in, it replaces the body of the function, then tries to call `PreCheckFunctionBuilderRequest` again, with the same function decl as before. It used to return cached "Success" result, but it didn't actually apply `PreCheckExpression`. So any `UnresolvedDeclRefExpr` remained unresolved. In this patch, make `PreCheckFunctionBuilderRequest` receive "body" of the function as well, so it doesn't return the cached result for the *previous* body. rdar://problem/65692922 (cherry picked from commit e953e52)

Cherry-pick of #32946 into
release/5.3PreCheckFunctionBuilderRequestonly useFunctionDeclas the cache key. Since fast-completion replaces the body of the function, the function decl alone is not sufficient for the key. Pass the body as well so that the request correctly evaluate the new body.
