  Log Message:
  -----------
  [CIR] Register only the LLVM IR translations CIR lowers to (#221797)

The ClangIR tests reach LLVM IR through mlir-translate, which links
every MLIR dialect and translation, so building check-clang builds most
of MLIR. Register mlir-to-llvmir in cir-translate over the same three
dialects and use it instead. Remove the dependency on `mlir-translate`
to run CIR tests.

ninja check-clang drops from 6499 to 5853 build edges.
