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
-
-tblgen - Target Description To C++ Code Generator
-
-=head1 SYNOPSIS
-
-B<tblgen> [I<options>] [I<filename>]
-
-=head1 DESCRIPTION
-
-B<tblgen> translates from target description (.td) files into C++ code that can
-be included in the definition of an LLVM target library. Most users of LLVM will
-not need to use this program. It is only for assisting with writing an LLVM
-target backend.
-
-The input and output of B<tblgen> is beyond the scope of this short
-introduction. Please see the I<CodeGeneration> page in the LLVM documentation.
-
-The F<filename> argument specifies the name of a Target Description (.td) file
-to read as input.
-
-=head1 OPTIONS
-
-=over
-
-=item B<-help>
-
-Print a summary of command line options.
-
-=item B<-o> F<filename>
-
-Specify the output file name.  If F<filename> is C<->, then B<tblgen>
-sends its output to standard output.
-
-=item B<-I> F<directory>
-
-Specify where to find other target description files for inclusion. The
-F<directory> value should be a full or partial path to a directory that contains
-target description files.
-
-=item B<-asmwriternum> F<N>
-
-Make -gen-asm-writer emit assembly writer number F<N>.
-
-=item B<-class> F<class Name>
-
-Print the enumeration list for this class.
-
-=item B<-print-records>
-
-Print all records to standard output (default).
-
-=item B<-print-enums>
-
-Print enumeration values for a class
-
-=item B<-gen-emitter>
-
-Generate machine code emitter.
-
-=item B<-gen-register-enums>
-
-Generate the enumeration values for all registers.
-
-=item B<-gen-register-desc>
-
-Generate a register info description for each register.
-
-=item B<-gen-register-desc-header>
-
-Generate a register info description header for each register.
-
-=item B<-gen-instr-enums>
-
-Generate enumeration values for instructions.
-
-=item B<-gen-instr-desc>
-
-Generate instruction descriptions.
-
-=item B<-gen-asm-writer>
-
-Generate the assembly writer.
-
-=item B<-gen-dag-isel>
-
-Generate a DAG (Directed Acycle Graph) instruction selector.
-
-=item B<-gen-subtarget>
-
-Generate subtarget enumerations.
-
-=item B<-gen-intrinsic>
-
-Generate intrinsic information.
-
-=item B<-version>
-
-Show the version number of this program.

-
-=head1 EXIT STATUS
-
-If B<tblgen> succeeds, it will exit with 0.  Otherwise, if an error
-occurs, it will exit with a non-zero value.
