Allow sharing middlesubstring if the terminator is present

[Bug #21983] Make &nil distinguishable from nonexistent block arg

[ruby/rubygems] Address review feedback on tmp directory path resolution

Use source_root.parent instead of hardcoded relative path to derive the
repository root, so the code remains correct if the support file is ever

Which was a contradiction as the pointer in the type specialization
should match the pointer on the right hand side.

ZJIT: Print CUInt64 in hex when sign bit is set

It's likely some sort of mask or flags. Hexadecimal is more compact.
