[lld] [llvm] [mlir] [polly] [NFC] Add explicit #include llvm-config.h where its macros are used, last part. (PR #107615)

[Daniil Fukalov via llvm-commits]

https://github.com/dfukalov created https://github.com/llvm/llvm-project/pull/107615

(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.
