When all the arguments of a template are elided, print "A<...>" instead of
"A<[2 * ...]>". Also remove comment fragment that means nothing.

When the template argument is both default and value dependent, the expression
retrieved for the default argument cannot be evaluated, thus never matching
any argument value. To get the proper value, get the template argument
from the desugared template specialization. Also, output the original
expression to provide more information about the argument mismatch.
