Short verison: no.

Longer version: Ports that depend on a specific LLVM version typically
do so because they link to LLVM libraries.  LLVM provides *no* API
stability between releases so programs can only link to a narrow range
of LLVM versions (1 version is common) and we can not ship the libraries
with the base system because we would then be stuck with a single LLVM
and clang version for the life of a STABLE branch (usually 5+ years).
