(this is the part related to bolt, lld and mlir)

Without these explicit includes, removing other headers, who implicitly include llvm-config.h, may have non-trivial side effects. For example, `clangd` may report even `llvm-config.h` as "no used" in case it defines a macro, that is explicitly used with #ifdef. It is actually amplified with different build configs which use different set of macros.
