Same things, this is a standard tool nowaday for any language
worth
considering. In fact, even if we had no specific support in D
for it,
C/C++ tooling could probably do it for us to some extent.

I use dmd with gprof with not-bad results. It's not perfect,
but at
least I can get some useful info out of it.
The built-in dmd profiler is unfortunately unusable for me
because its
function call counters wrap around far too early (IIRC they use
16-bit
counters or something like that), whereas the test cases I need
to
optimize for are the long-running, steady state test cases in
which
millions or billions of function calls are made.
Will this ever be improved?

have you tried oprofile? It's embarrassingly simple to use,
especially compared to perf. oprofile used to be much worse though
