Fix a crash when evaluating a constexpr function which contains
recovery-exprs. https://bugs.llvm.org/show_bug.cgi?id=46837

Would be nice to have constant expression evaluator support general template
value-dependent expressions, but it requires more work.

This patch is a good start I think, to handle the error-only
value-dependent expressions.
