When visiting the AST to add counters, there are special cases in which
the code calls cuts the walking short by returning nil. In some cases
certain nodes are ignored, e.g. Init and Cond inside IfStmt.
The fix is to explicitly walk all the children nodes (not only
Body and Else) when cutting the current walk. Similar approach
was taken with SwitchStmt and TypeSwitchStmt.
While the existing test code doesn't handle different counters in the
same line, the generated HTML report does it correctly (because it takes
column into account).
The previous behavior caused lines in function literals to not be
tracked when those literals were inside Init or Cond of an IfStmt for
example.
Fixes#14039.

Usually, you are primarily interested to see the coverage of a particular
file (e.g. when you're changing tests that affects a given source file),
it is very valuable if you can just refresh the page and immediately see
changes to the part you're already looking at (without selecting from the
selector again.)

Forgot to update the references to the old cover package. No excuse.

This required dealing with the ill-advised split of the profile code
into a separate package. I just copied it over unchanged. The package
does not deserve to be in the standard repository. We can cope
with the duplication.
Also update the go command to know about the new location.
Fixes#10528.
