llvm.eclass: Set LLVM_SLOT in pkg_setup()
Set LLVM_SLOT in pkg_setup() to the selected LLVM slot, for inspection from the package. For example, it can be used to easily compare the version number. Split get_llvm_slot() out of get_llvm_prefix() to factor out the common code. Signed-off-by: Michał Górny <mgorny@gentoo.org>
