Hi,
I believe that using fold_convert instead of fold_build1 means that we would
bypass folding done in fold_unary that handles stuff like two conversions in a
row while fold_convert is primarily about returning constant when result is
constant.

Since I want to avoid wrapping fold calls all frontends except for C++
consistently put around convert_to_* calls, I want to do this kind of folding.

I believe only reason to avoid folding is C++ template stuff.
