[llvm-dev] Deprecation of the LLVM SVN server

[Mehdi AMINI via llvm-dev]

I generated apache2 rewrite rules for these URLs to redirect to the
monorepo equivalent:

$ git rev-list 40c47680eb2a1cb9bb7f8598c319335731bd5204  | while read
commit ; do SVNREV=$(git log --format=%B -n 1 $commit | grep '^llvm-svn:
[0-9]*$' | awk '{print $2 }') ; [[ ! -z "$SVNREV" ]] && echo "RewriteRule
^/rL$SVNREV /rG$commit [R=301,L]" ;  done
RewriteRule ^/rL375504 /rG40c47680eb2a1cb9bb7f8598c319335731bd5204 [R=301,L]
RewriteRule ^/rL375503 /rG3ef017d0669e0dfa7e34a6e58d80c8f307db6d8c [R=301,L]
RewriteRule ^/rL375502 /rG95290827d7d01c63ac57b2cf5204215ba4ee4b06 [R=301,L]

It's in place now on phabricator.
