Subject: [PATCH 2/2] Fix require issue with file extension priority
If `require "a"` is run when two folders have been specified in the -I
option including a "a.rb" file and a "a.so" file respectively, the ruby
spec says that the ".rb" file should always be preferred. However, the
logic we added in https://github.com/rubygems/rubygems/commit/6b81076d9
to make the -I option always beat default gems does not respect this
spec, creating a difference from the original ruby-core's require.
[the ruby spec says]: https://github.com/ruby/spec/blob/d80a6e2b221d4f17a8cadcac75ef950c59cba901/core/kernel/shared/require.rb#L234-L246

Subject: [PATCH 4/5] Fix `$LOADED_FEATURES` cache sometimes not respected
In the cases where the initial manually `-I` path resolution succeeded,
we were passing a full path to the original require effectively skipping
the `$LOADED_FEATURES` cache. With this change, we _only_ do the
resolution when a matching requirable path is found in a default gem. In
that case, we skip activation of the default gem if we detect that the
required file will be picked up for a `-I` path.

Subject: [PATCH 2/3] Fix bug bug calculating $LOAD_PATH's to check in
`require`
In `Gem.load_path_insert_index` is not set, we end up having
`$LOAD_PATH[0...-1]`, unintentionally skipping the last $LOAD_PATH entry
from the check.
The correct thing to do in that case is to not even try since we have no
way of distinguisng default LOAD_PATH entries from those added with -I.

Subject: [PATCH] Revert "Exclude empty suffix from `-I` require loop"
This reverts commit 4fc0ab21c0f7713829abb522ce3b6d8e24c126b3.
Technically, extensionless ruby files are valid ruby files that can be
required. For example, `bin/bundle` is sometimes required from other
binstubs even if it's also runnable directly.
So, we should technically consider this kind of files too.
