[PATCH] CMake: add LLVM_INSTALL_LIBRARIES variable

[Hans Wennborg]

Hi rnk,

This variable controls whether the LLVM libraries and headers files should be part of the 'install' target. Excluding them is useful for creating a smaller installation package.

This also adds LLVM_INSTALL_TABLEGEN which can be used to exclude the tablegen binaries from the 'install' target for the same reason.

If this looks OK, I have patches to exclude Clang and lld libraries/headers in the same way.
