Fix bogus "emit without supply or react" in Supplier's TapList

Avoid auto-vivification of the Scalar container for the $!tappers attribute when reading. That could lead to a Mu overwriting the list in $!tappers after we've already set $added to True in method tap, causing us to blow up when we try to call .emit on that Mu.

Try to rename precomp files multiple times on Windows

File renaming can easily race and fail on Windows. There's no great solution, so instead just try 10 times catching a failure (and returning out of the loop and method if it succeeds), and if it hasn't succeeded after that, try one more time without catching a failure.		 07:42

Introduce "done foo" as shortcut for "emit foo; done" (#4412)

As discussed in github.com/Raku/problem-solving/issues/249
This makes the "done" sub a multi and adds a candidate that does an `emit` of the value, before actually doing a `done`.		 09:34

nine lizmat: has Mu $!tappers is built(False) is built(:bind) = Mu; looks interesting. I just don't understand it :D. But then, I'm quite ironically actually not that good a Raku programmer. I tend to write kind of baby Raku 10:21
lizmat well... actually it's a roundabout way to abuse the standard object build process

And implement compilation of the most common cases of it, for `>>++` (a simple postfix) and `>>.meth` (a simple method call). There are various other less common cases that shall need attention.

Fix issue with grep when storing result in array

Basically, the grep wrapper was only working correctly if the iterator was just being called with "pull-one", but would fail to end if the
  "push-all" method was called on the iterator (my @a = foo.grep...).
The fix was to have the LAST handler in the grep wrapper for Callables throw another "last" with the correct value to be handled by the outer handler.		 18:11
