Add $?DISTRIBUTION (#2574)

Add a variable to give module authors a way to access *any* file in their distribution as well as the distribution meta data.
It might seem like `$?FILE` can provide everything required, but some `CompUnit::Repository` may not have an e.g. on-disk representation of the files listed in the meta data -- this allows IO access using the file names as listed in the meta data regardless of the `CompUnit::Repository` that loaded it.
Some uses:
  * `say "Version: " ~ $?DISTRIBUTION.meta<ver>`
  * `$?DISTRIBUTION.content('lib/Any/Module/In/Distribution.pm6').open.slurp(:close)`
  * `$?DISTRIBUTION.content('resources/libraries/p5helper').open.slurp(:close)` ( similar to `%?RESOURCES<libraries/p5helper>.IO.open.slurp(:close)` )

camelia Ambiguous call to 'a(A: )'; these signatures all match:
:(A: *%_)

in block <unit> at <tmp> line 1
lizmat feels to me both should be giving the ambiguous call error ? 13:21
nine robertle: spesh bugs can be sensitive to timing since spesh runs in a separate thread
timotimo you can use MVM_SPESH_BLOCKING to prevent timing sensitivity from being a problem 13:23
instead of shoving work off to another thread and going on with its life, it'll wait for the other thread to finish that particular piece of work
i like using it when i run benchmarks 13:32

lizmat AlexDaniel: well, it's been documented since June, and it's been in 2 R* releases 18:38
I'm a bit reluctant to change it (again) now, as I want to use it in my P5 modules...
which I now more or less can, because it is in 2 R* releases 18:39
AlexDaniel lizmat: yeah but maybe we can have an alias?
lizmat I'm neutral on that, perhaps jnthn has a better opinion on that 18:41
just to be clear: I wanted something that would allow some p5isms to be valid if needed, e.g. in conjunction with P5 modules
hence I called it "use p5isms" originally, which Zoffix then suggested we'd generalize 18:42
the $a=~$b case is different in that it is, in and of itself, valid Perl 6 code 18:43

lizmat is it me, or is -I. currently broken ? 19:31
given a Foo.pm6 in the current dir, "perl6 -I. -e 'use Foo'" fails for me with: 19:32
Cannot resolve caller new(IO::Path:U: Any:U, :CWD(Str)); none of these signatures match:
if the module doesn't exist, it fails properly 19:33
if it is in another directory, it all works ok: seems to be limited to using "-I.", at least for me 19:34
ugexe pointed out I probably had a META6.json file in the dir of -I , and he was right 20:05

that would sorta require for .WHAT to become a real method, which it isn't 22:08
