Turn output of -vtemplates into compiler-messages and show template instances

D just got a better formatting of existing template usage sorted by descending unique instantiation count via the flag `-vtemplates`. Each template that has a least one instantiation is now printed using standard compiler diagnostics formatting for easy navigation to the point of its declaration.

Additionally, a new feature is to instead of

    `-vtemplates`

use

    `-vtemplates=list-instances`

. Then the location(s) for each instance of each instantiated template is printed along with information telling whether the instantiation was implicit or explicit.

A good example of the behavior can be found in the test file [2]

Nice.

People also might find it useful to filter for just one template (and show all the instances).

I proposed that feature as, say,

    `vtemplates=list-instances:Template1,Template2,...`

. Just complain a bit and I'll get momentum to add that too ;)
