Subject: [PATCH] dev-util/lldb: Introduce the initial live version

Introduce an initial live ebuild for split LLVM debugger package.
The version should build and work fine to the degree of old LLVM
ebuilds. Tests are not yet implemented, Python readline module needs to
be thought over and static libraries need to be replaced with shared.
