Because the LLVM [coding guidelines](https://llvm.org/docs/CodingStandards.html#header-guard) for include guards only talk about that path that would be used when including the file.  `LLVM` isn't part of that.

(The guidelines don't say what to do for headers that are outside the `include` directory, such as those in `clang/lib/CIR/CodeGen`.  So I have been leaving the `LLVM` in those include guard macros.)
