Overhauled llvm/clang docs builds. Closes PR6613.

NOTE: 2nd part changeset for cfe trunk to follow.

*** PRE-PATCH ISSUES ADDRESSED

- clang api docs fail build from objdir
- clang/llvm api docs collide in install PREFIX/
- clang/llvm main docs collide in install
- clang/llvm main docs have full of hard coded destination
  assumptions and make use of absolute root in static html files;
  namely CommandGuide tools hard codes a website destination
  for cross references and some html cross references assume
  website root paths

*** IMPROVEMENTS

- bumped Doxygen from 1.4.x -> 1.6.3
- splits llvm/clang docs into 'main' and 'api' (doxygen) build trees
- provide consistent, reliable doc builds for both main+api docs
- support buid vs. install vs. website intentions
- support objdir builds
- document targets with 'make help'
- correct clean and uninstall operations
- use recursive dir delete only where absolutely necessary
- added call function fn.RMRF which safeguards against botched 'rm -rf';
  if any target (or any variable is evaluated) which attempts
  to remove any dirs which match a hard-coded 'safelist', a verbose
  error will be printed and make will error-stop.

+=head1 NAME
+
+llvm-ranlib - Generate index for LLVM archive
+
+=head1 SYNOPSIS
+
+B<llvm-ranlib> [--version] [-help] <archive-file>
+
+=head1 DESCRIPTION
+
+The B<llvm-ranlib> command is similar to the common Unix utility, C<ranlib>. It
+adds or updates the symbol table in an LLVM archive file. Note that using the
+B<llvm-ar> modifier F<s> is usually more efficient than running B<llvm-ranlib>
+which is only provided only for completness and compatibility. Unlike other 
+implementations of C<ranlib>, B<llvm-ranlib> indexes LLVM bitcode files, not
+native object modules. You can list the contents of the symbol table with the
+C<llvm-nm -s> command.
+
+=head1 OPTIONS
+
+=over
+
+=item F<archive-file>
+
+Specifies the archive-file to which the symbol table is added or updated.
+
+=item F<--version>
+
+Print the version of B<llvm-ranlib> and exit without building a symbol table.
+
+=item F<-help>
+
+Print usage help for B<llvm-ranlib> and exit without building a symbol table.
+
+=back
+
+=head1 EXIT STATUS
+
+If B<llvm-ranlib> succeeds, it will exit with 0.  If an error occurs, a non-zero
+exit code will be returned.
