With this patch, llvmbuild no longer needs to be invoked during cmake runs.

Notes:

- Try this by passing `WITHOUT_LLVMBUILD=ON`, e.g.,

  ```bash $ mkdir build; cd build $ cmake -G Ninja -D WITHOUT_LLVMBUILD=ON ${other_cmake_flags} ..` $ ninja as usual ```

- LLVM components are expected to be libraries whose names begin with "LLVM," case sensitive.

- Component dependencies are now passed into `LLVM_`-/`LINK_COMPONENTS`. Either:

  ```cmake set(LLVM_LINK_COMPONENTS LLVMLibraryName Core Support Demangle ...) add_llvm_library(LLVMLibraryName src0.cpp src1.cpp ...) ```

  or

  ```cmake add_llvm_library(LLVMLibraryName src0.cpp src1.cpp ... LINK_COMPONENTS LLVMLibraryName Core Support Demangle ... ) ```

  Arguments to `*LINK_COMPONENTS` are now case sensitive because we no longer have the benefit of llvmbuild's pre-computed dependencies.

- `LibraryDependencies.inc`, required by llvm-config, is now built by `LLVMBuild.cmake` after all component dependencies are collected and checked
