Add Claude Explain feature for AI-powered code explanations
This PR introduces Claude Explain, a new feature that provides AI-powered explanations of compiler output directly within Compiler Explorer.
Key features:
Claude Explain functionality:
- New explain view pane
- Explains compiler output with full context of source code and compilation output
- Configurable audience level and explanation type
- Response caching to improve performance and reduce API calls
- Usage statistics display showing requests used and token counts
User experience:
- Consent flow on first use explaining data handling and privacy
- AI disclaimer banner warning about potential LLM inaccuracies
- Respects "no-ai" directive in source code for users who don't want AI processing
Privacy and security:
- Data sent to Anthropic's Claude API as documented in privacy policy
- No data used for model training
- Clear consent required before first use
- Support for opting out via "no-ai" directive
The feature is marked as beta and can be enabled via configuration.

This patch adds two options to the clangir pane that affects the clangir
compilation pipeline:
* Flat CIR enables the emission of flat clangir CFG;
* -fclangir-mem2reg enables the mem2reg pass on the flat clangir CFG.
Currently the clangir compiler is implemented by a special clang variant
whose compilation options list gets appended with `-Xclang -fclangir
-Xclang -emit-cir`. This introduces a problem: we no longer gets access
to its LLVM IR output and assembly output because `-emit-cir` is an
exclusive option.
This patch resolves this problem by introducing a new ClangIR pane,
similar to the LLVM IR pane or Rust MIR pane. A new output kind named
`ClangIR` is added to the "Add new..." drop down menu and it toggles the
ClangIR pane. This patch then removes `-Xclang -emit-cir` from the
options list of the clangir compiler. The clangir compiler will then
output assembly code just like other clang compilers. The removed
options will be added back when compiled from the ClangIR pane.
This prepares for future work that will reuse the opt pipeline view
outside of the LLVM ecosystem by renaming related components to remove
the LLVM prefix.
The pass dumper keep its LLVM prefix, as it is assumed this part is
likely to be customised for each compiler ecosystem.
The historical component name has been preserved in the component list
as an alias to keep old links working.
* Move popup views to their own file each
* Make simple monacopane mixin in templates
* Also extract templates to their files
Compiler got some mixin love too :)
* Also split templates to their own files
* More mixin love for more files
