CMake: enable installing utils

[mtrofin]

Summary

Added a new boolean CMake flag, LLVM_INSTALL_UTILS. When set,
the 'install' target will include in the bin directory the
utils binaries - e.g. FileCheck. This mirrors the autoconfig
behavior.

LGTM, maybe Chris has a comment, as he's been working on CMake lately.

I would add COMPONENT arguments here to set the install component, and I would add custom install targets.

For an example see: AddLLVM.cmake:416-424.

Incorporated feedback:

• COMPONENT argument
• custom install targets

Sorry to nitpick, but you want to wrap this in:

if (NOT CMAKE_CONFIGURATION_TYPES)

That way you won't be creating an unwieldy number of extra targets for IDE users.

[mtrofin]

I see. I didn't fully grasp that nuance, thanks for clarifying!

Wrapped the custom install target

[beanz]

LGTM. Thanks!

Thank you!
