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-nm - list LLVM bitcode file's symbol table
-
-=head1 SYNOPSIS
-
-B<llvm-nm> [I<options>] [I<filenames...>]
-
-=head1 DESCRIPTION
-
-The B<llvm-nm> utility lists the names of symbols from the LLVM bitcode files,
-or B<ar> archives containing LLVM bitcode files, named on the command line.
-Each symbol is listed along with some simple information about its provenance.
-If no file name is specified, or I<-> is used as a file name, B<llvm-nm> will
-process a bitcode file on its standard input stream.
-
-B<llvm-nm>'s default output format is the traditional BSD B<nm> output format.
-Each such output record consists of an (optional) 8-digit hexadecimal address,
-followed by a type code character, followed by a name, for each symbol. One
-record is printed per line; fields are separated by spaces. When the address is
-omitted, it is replaced by 8 spaces.
-
-Type code characters currently supported, and their meanings, are as follows:
-
-=over
-
-=item U
-
-Named object is referenced but undefined in this bitcode file
-
-=item C
-
-Common (multiple definitions link together into one def)
-
-=item W
-
-Weak reference (multiple definitions link together into zero or one definitions)
-
-=item t
-
-Local function (text) object
-
-=item T
-
-Global function (text) object
-
-=item d
-
-Local data object
-
-=item D
-
-Global data object
-
-=item ?
-
-Something unrecognizable
-
-=back
-
-Because LLVM bitcode files typically contain objects that are not considered to
-have addresses until they are linked into an executable image or dynamically
-compiled "just-in-time", B<llvm-nm> does not print an address for any symbol,
-even symbols which are defined in the bitcode file.
-
-=head1 OPTIONS
-
-=over
-
-=item B<-P>
-
-Use POSIX.2 output format. Alias for B<--format=posix>.
-
-=item B<-B>    (default)
-
-Use BSD output format. Alias for B<--format=bsd>.
-
-=item B<-help>
-
-Print a summary of command-line options and their meanings.
-
-=item B<--defined-only>
-
-Print only symbols defined in this bitcode file (as opposed to
-symbols which may be referenced by objects in this file, but not
-defined in this file.)
-
-=item B<--extern-only>, B<-g>
-
-Print only symbols whose definitions are external; that is, accessible
-from other bitcode files.
-
-=item B<--undefined-only>, B<-u>
-
-Print only symbols referenced but not defined in this bitcode file.
-
-=item B<--format=>I<fmt>, B<-f>
-
-Select an output format; I<fmt> may be I<sysv>, I<posix>, or I<bsd>. The
-default is I<bsd>.
-
-=back
-
-=head1 BUGS
-
-B<llvm-nm> cannot demangle C++ mangled names, like GNU B<nm> can.
-
-=head1 EXIT STATUS
-
-B<llvm-nm> exits with an exit code of zero.
