x86_64 build error converting poly_value_estimate_kind

[Martin Sebor via Gcc-patches]

The top of trunk fails to build with the error below.  I haven't
spent any time debugging it except to look at git log where
the description for r11-6238 mentions the function also referenced
in the error message.  Could the patch be responsible for this?
