435d499177 Use VLD2q32 / VST2q32 to reload / spill QQ (pair of Q) registers when stack slot is sufficiently aligned. Use VLDMD / VSTMD otherwise.

07a6d9391c 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.

0d881042c0 When rematerializing, use the debug location of the original
instruction, rather than a location near where the new instruction
is being inserted.

68cb31901c 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.

decoded correctly.

c52edc7d30 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.

62bb2f63f9 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.
