Fix X::Assignment::RO message when assignment to Nil is attempted

There was two issues:
  - Nil was passing a string with its name as the problematic value
  - The exception wasn't designed to accept `Nil` as a value
Resolves #4586
rakudo: 1ea47322a2 | (Vadim Belman)++ | src/core.c/Exception.pm6
Make X::Assignment::RO $!value required

It was previously initialized with a "value" string.

japhb Where's a good place for uploading temporary *images*? (Like gists, but for screenshots) 15:06
MasterDuke spectacle has an option to anonymously upload a screenshot to imgur 15:09

japhb Interestingly, I also see similarly-shaped improvements for test-t-20 and test-t-20 --race, but *not* for test-t --race (or at least, not enough to counteract the slowdown over the last quarter). 15:35

Geth nqp/dispatcher-replace-arg-syscall: 82594548eb | (Timo Paulssen)++ | src/core/dispatchers.nqp
replace drop-arg + insert-arg with replace-arg

in a few dispatchers that nqp uses. Once there is a replace arg with literal values, that could be used in more places.

Add a IterationBuffer.new(iterable) candidate

To facilitate initializing iteration buffers. Makes
   IterationBuffer.new(<a b c d e f g h i j>);
about 2x as fast as:
   my $b := IterationBuffer.new;
   $b.push($_) for <a b c d e f g h i j>;

Geth rakudo: 0dae67a60d | (Elizabeth Mattijsen)++ | src/core.c/Cool.pm6
Make .subst upto 1.9x as fast

Because new-disp allows removal of the nqp::getlexcaller hack in the proto to be able to access the $/ in the caller from a dispatched method. This making it an empty proto, which apparently in new-disp, doesn't even exist call stack-wise.

Make .subst-mutate faster by simplifying proto
lizmat actually, that one accidentally also included .trans
ugexe: if I have just installed a module with `zef install .`, is it to be expected that the first time an installed script loads that module, that it gets compiled again ? 19:55
(judging from what I see with --stagestats, which sadly doesn't mention the name of the module being parsed, could that be fixed?)
ugexe if the script has something like `use lib ...` sure 19:59
lizmat and when it doesn't?
ugexe well if you install zef and run zef --help you'll see it doesnt recompile anything 20:00

nine Actually just use lib shouldn't cause any recompilation. Except if the lib contains some dependency of the installed module 20:35
What will happen on the first run is re-checking of dependencies. So the first run will be slower but not terribly much. 20:37
lizmat well.. after a recompile of rakudo, restarting the irc logs server takes about a minute :-( 20:38
nine Well that is to be expected. In that case we have to recompile all used modules and Cro alone is quite a bit of code 20:42
lizmat yeah... running it with --stagestats shows it's going at least 6 levels deep 20:44
Geth nqp/dispatcher-replace-arg-syscall: c9ef29a218 | (Timo Paulssen)++ | src/core/dispatchers.nqp
use replace-arg-literal-obj in nqp's dispatchers
ugexe yeah i wasnt quiet clear... i meant `use lib "."` or `use lib "lib"` (which if either was in code installed by `zef install .` would get picked up as a dependency 20:59
