Warn when the conversion of an integral non-type template argument to
the type of its corresponding non-type template parameter changes the
value. Previously, we were diagnosing this as an error, which was
wrong. We give reasonably nice warnings like:
test/SemaTemplate/temp_arg_nontype.cpp:100:10: warning: non-type template
argument value '256' truncated to '0' for template parameter of type
'unsigned char'
Overflow<256> *overflow3; // expected-warning{{non-type template ...
^~~
test/SemaTemplate/temp_arg_nontype.cpp:96:24: note: template parameter is
declared here
template<unsigned char C> struct Overflow;
