  [DAG] Ensure more Legal BUILD_VECTOR elements types in shuffle->And combine

This is a followup to D131350, which caused another problem for i64
types being split into i32 on i32 targets. This patch tries to make sure
that either Illegal types are OK, or that the element types of a
buildvector are legal and bigger than or equal to the size of the
original elements.

  [llvm] [cmake] Move LLVM_INSTALL_PACKAGE_DIR top-level to fix llvm-config

Move the `LLVM_INSTALL_PACKAGE_DIR` declaration from llvm/cmake/modules
directory to the top-level llvm/CMakeLists.txt, in order to fix
the regression in `llvm-config --cmakedir` output for installed LLVM.
Since the tools directory is processed by CMake prior to
llvm/cmake/modules, the llvm-config executable ended up using
the variable prior to it being defined and incorrectly used an empty
path, resulting in e.g.:

    $ llvm-config --cmakedir

With this patch, the path is defined (and therefore the default value
is being set) prior to adding the tools subdirectory and llvm-config
starts working correctly:

    $ llvm-config --cmakedir

This fixes a regression introduced by D130539.  Thanks to Petr Polezhaev
