Improve the error message when a function overload candidate is rejected
because it expects a reference and receives a non-l-value.
For example, given:
int foo(int &);
template<int x> void b() { foo(x); }
clang will now print "expects an l-value for 1st argument" instead of
"no known conversion from 'int' to 'int &' for 1st argument". The change
in wording (and associated code to detect the case) was prompted by
comment #5 in PR3104, and should be the last bit of work needed for the
bug.
