[WIP][clang][Fuchsia] Add the *-fuchsia-gnu arch and multilibs

[leonardchan]

Summary

Create libraries that are GCC compatible as part of the Fuchsia toolchain.

I'd just iterate over full triples rather than doing the .*_gnu replacement, see above what we do for Linux. The same below.

219–236

I'd break this off into a separate foreach loop and only do it for the non-GNU variant.

clang/test/Driver/fuchsia.cpp

104–119

I don't think we need these multilibs for the GNU variant.
