Cthulhu v3.0.0

Diff since v2.17.10

Cthulhu 3.0.0 marks a major redesign of its internals with respect to how downstream packages customize Cthulhu's introspection features for their own types. Previously, the interface was established on Compiler.AbstractInterpreter; now, it uses a dedicated Cthulhu.AbstractProvider interface type, with a clearer and more powerful interface. Documentation on the whole interface is accessible via ?AbstractProvider. The PRs introducing the breaking changes are #662, and its follow-up #677.

See the CHANGELOG.md for other details. The main breakages that users may encounter are the following:

• The annotate_source configuration option was removed in favor of a view::Symbol configuration option, with the :source|:ast|:typed|:llvm|:native available views by default (more may be defined by providers).
• The exception_type configuration option was renamed to exception_types for consistency with remarks.
• The with_effects configuration option was renamed to effects for consistency with remarks and exception_types.
• The inline_cost configuration option was renamed to inlining_costs, also for consistency reasons.
• The interruptexc configuration option was removed. It used to control whether q exited (by throwing an InterruptException) or ascended, but now that backspace was added as a shortcut to ascend, we can now unconditionally exit with q (which actually matches its action description).
