Rollup merge of #127654 - nikic:llvm-ndebug-fix, r=cuviper 
Fix incorrect NDEBUG handling in LLVM bindings

We currently compile our LLVM bindings using `-DNDEBUG` if debuginfo for LLVM is disabled. However, `NDEBUG` doesn't have any relation to debuginfo, it controls whether assertions are enabled.

Split the LLVM_NDEBUG environment variable into two, so that assertions and debuginfo are controlled independently.

After this change, `LLVMRustDIBuilderInsertDeclareAtEnd` triggers an assertion failure on LLVM 19 due to an incorrect cast. Fix it by removing the unused return value entirely.

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
