Revert "Fix LLVM_ENABLE_ABI_BREAKING_CHECKS macro check: use #if inst… (#110923)
…ead of #ifdef (#110883)" This reverts commit 1905cdb, which causes lots of failures where LLVM doesn't have the right header guards. The errors can be seen on [BuildKite](https://buildkite.com/llvm-project/upstream-bazel/builds/112362#01924eae-231c-4d06-ba87-2c538cf40e04), where the source uses `#ifndef NDEBUG`, but the content in question is defined when `LLVM_ENABLE_ABI_BREAKING_CHECKS == 1`. For example, `llvm/include/llvm/Support/GenericDomTreeConstruction.h` has the following: ```cpp // Helper struct used during edge insertions. struct InsertionInfo { // ... #ifdef LLVM_ENABLE_ABI_BREAKING_CHECKS SmallVector<TreeNodePtr, 8> VisitedUnaffected; #endif }; // ... InsertionInfo II; // ... #ifndef NDEBUG II.VisitedUnaffected.push_back(SuccTN); #endif ```
