859a6d2135 Use VSTMD / VLDMD for spills and reloads of Q registers instead of VSTMQ / VLDQ. The later are aliases which ought to be eliminated but we can't because they are used for storing and loading v2f64 values.

6b8861e9f6 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.

4331428e24 Eliminated the classification of control registers into %ecr_

decoded correctly.

8d0b53dc62 Fix handling of unreachable blocks in the SSAUpdater. The previous code only 
handled cases where a block had zero predecessors, but failed to detect other
cases like loops with no entries.  The SSAUpdater is already doing a forward
traversal through the blocks, so it is not hard to identify the blocks that
were never reached on that traversal.  This fixes the crash for ppc on the
stepanov_vector test.

a3731b17c0 Revert r103137, fix for $ in labels. It looks like we can't actually handle this

  .globl $a
  movl ($a), %eax
  movl $a, %eax
  movl $$a, %eax

07a622c7b6 Fixes a coalescer bug that caused llc to crash on 2009-11-30-LiveVariablesBug.ll 
with the fix in 103157.

%reg1039:1<def> = VMOVS %S1<kill>, pred:14, pred:%reg0
is not coalescable since none of the super-registers of S1 are in reg1039's
register class: DPR_VFP2. But it is still a legal copy instruction so it should
not assert.
