11:30 PM Ruby Revision bc40e758 (git): Interpolated strings must not be frozen

Strings concatenated with backslash may end up being frozen when they
shouldn't be. This commit fixes the issue. It required a change
upstream in Prism, but also a change to the Prism compiler in CRuby.

09:37 PM Ruby Revision 2b23b05b (git): ZJIT: Add a specialized instruction iterator to the assembler

This commit adds a specialized instruction iterator to the assembler
with a custom "peek" method. The reason is that we want to add basic
blocks to LIR. When we split instructions, we need to add any new
instructions to the correct bas... tenderlovemaking (Aaron Patterson)

09:37 PM Ruby Revision d7e55f84 (git): ZJIT: Use the custom iterator

This commit uses the custom instruction iterator in arm64 / x86_64
instruction splitting. Once we introduce basic blocks to LIR, the
custom iterator will ensure that instructions are added to the correct
place. tenderlovemaking (Aaron Patterson)

04:03 AM Ruby Revision 917e77be (git): [ruby/rubygems] Deprecate comparing Gem::Version objects with strings

Comparing version objects is a huge bottleneck in dependency solvers
(like inside Bundler). I would like to make comparing version objects
cheaper. Right now we support comparing version objects with strings by
trying to coerce the str... tenderlovemaking (Aaron Patterson)

04:53 AM Ruby Revision 5ccaeee2 (git): [ruby/rubygems] Undeprecate `Gem::Version.new(nil)`

It seems like we were trying to deprecate passing `nil` to
Gem::Version.new. This breaks existing code, and I don't think there is
a good reason to deprecate this usage.
I believe what we want to prevent is the following code:

04:57 AM Ruby Revision d3138912 (git): [ruby/rubygems] build gems directly instead of shelling out

I'm trying to speed up the bundler tests. The tests shell out a lot in
order to build gems. We can build gems without creating a sub-process.
This change reduced the test suite time from ~24 minutes, to about ~21
minutes on my machine. ... tenderlovemaking (Aaron Patterson)
