includes word break characters
(https://github.com/ruby/irb/pull/523)
* Improve method completion for string and regexp that includes word break characters
* Remove completion-test's assert_not_include because candidates no longer include every possible methods
* Add comment about string's method completion regexp

It's not really about different compilers. It seems confusing to have
this in compilers.yml.
This change only forks the entire workflow and modifies only matrix
entries.
We used `url` field for testing via git clone. Because `Gem::Specification#homepage` or
`Gem::Specification#metadata` could assign non-git url. Unfotunately, We should specify
clone URL for testing.
Current implementation tried to build installation artifact. But default gems
didn't provide normal gem files. So, It's always build failure.

Consider completion for this example: `foo.bar.b`
Without type information, it is hard to know the return value of the `bar`
method, so the current implementation interates through `ObjectSpace` to
get all possible candidates for the second method.
In small projects, the performance and accuracy are acceptable. But in
bigger projects, the performance is unacceptable and the accuracy is mostly
poor.
So this commit drops the support for chained methods' completion.
The following script can sometimes trigger a crash:
```ruby
GC.stress = true
class Array
def foo(bool)
if bool
@a = 1
@b = 2
@c = 1
else
@c = 1
end
end
end
obj = []
obj.foo(true)
obj2 = []
obj2.foo(false)
obj3 = []
obj3.foo(true)
```
This is because vm_setivar_default calls rb_ensure_generic_iv_list_size
to resize the iv list. However, the call to gen_ivtbl_resize reallocs
the iv list, and then inserts into the generic iv table. If the
st_insert triggers a GC then the old iv list will be read during
marking, causing a use-after-free bug.
