The catch entry block has all locals in fixed locations
(Rj) where j = kNumberOfRegisters - i for parameter i.
This means we reserve a range of DBC registers at the top-end of the frame.
Those registers are blocked for general allocation to avoid any overlap
with the rest of the registers that are allocated from the bottom.
Each optimized frame with a try-catch will be kNumberOfRegisters wide.

My initial goal was just to move some of the HTML tests off unittest,
but that ended up slurping in some other changes as well. I haven't
finished going through all of the tests, but this puts the
infrastructure in place and fixes a batch of them. I'll do more next.
Changes:
- Add a "minitest" package. This shims just enough of the unittest/test
API to make it easy to swap it out for unittest without having to
rework the entire test.
- Go through the HTML tests from A-J and change them to use minitest
when possible. The ones that aren't possible use asynchrony.
Minitest doesn't support async tests (yet, maybe).
- Triage those tests and enable ones that are passing. Mark them failing
if failing. Filed a couple of tracking bugs for the common issues,
but for other cases, I just left a comment.
- In the process of this, I went ahead and make some of the affected
tests strong mode clean if they weren't already and it was easy.
- Synchronize changes between dev_compiler's fork of expect and
pkg/expect. We'll want to unfork those at some point. D-:
This gets dev_compiler from 1985 tests to 2042.

- [x] Make `reloadSources` RPC public.
- [x] Add an optional 'pause' parameter to `reloadSources`. When set to true, the isolate will enter the debug pause loop immediately after reloading sources and before resuming execution. This makes it possible for debugger clients to set breakpoints before resuming.
- [x] Add reload_sources_test which tests pausing after reload.
- [x] Fix a bug in `GetVarDescriptors` where a null code object could be used.

This makes the following improvements:
* Always show the call that was made, with arguments.
* ...and show the actual arguments in more cases.
* Be less confusing in the case of a call on the null receiver.
* Be less redundant in the output.
* Report when a constructor is called with the wrong number of arguments.

Wait for concurrent sweep tasks before verifying points, as building the allocation set expects unmarked objects.
Make assertion okay with a missing stack map at entry, which transiently exists for OSR, as the frame looks the same as unoptimized code here.

Flutter layout benchmark 14k us -> 10k us. ~30%
improvement in checked mode. There still appear
to be a lot of checks that should be hitting the
cache, so there may be other fast-paths needed
as well.

If there is no override of noSuchMethod in any class, we can
propagate the receiver type downwards from calls that call a unique
selector.
This speeds up dart2js by around 3%, a particle simulation benchmark by around 10%.
