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.

+@section main_intro Introduction
+Welcome to the Low Level Virtual Machine (LLVM).
+
+<br>
+This documentation describes the @b internal software that makes 
+up LLVM, not the @b external use of  LLVM. There are no instructions
+here on how to use LLVM, only the APIs that make up the software. For usage 
+instructions, please see the programmer's guide or reference manual.
+
+@section main_caveat Caveat 
+This documentation is generated directly from the source code with doxygen. 
+Since LLVM is constantly under active development, what you're about to
+read is out of date! However, it may still be useful since certain portions
+of LLVM are very stable. 
+
+@section main_changelog Change Log

-/// @mainpage Low Level Virtual Machine
-///
-/// @section main_intro Introduction
-/// Welcome to the Low Level Virtual Machine (LLVM).
-///
-/// This documentation describes the @b internal software that makes 
-/// up LLVM, not the @b external use of  LLVM. There are no instructions
-/// here on how to use LLVM, only the APIs that make up the software. For usage 
-/// instructions, please see the programmer's guide or reference manual.
-///
-/// @section main_caveat Caveat 
-/// This documentation is generated directly from the source code with doxygen. 
-/// Since LLVM is constantly under active development, what you're about to
-/// read is out of date! However, it may still be useful since certain portions
-/// of LLVM are very stable. 
-///
-/// @section main_changelog Change Log
