6909ecf66e Extend the AliasAnalysis::pointsToConstantMemory interface to allow it 
to optionally look for constant or local (alloca) memory.

Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select
and Phi nodes, and to support looking for local memory.

Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that
AliasAnalysis knows all the tricks that it knew.

5d1361e9ed Reimplement BuildResultOperands to be in terms of the result instruction's 
operand list instead of the operand list redundantly declared on the alias
or instruction.

With this change, we finally remove the ins/outs list on the alias.  Before:
  def : InstAlias<(outs GR16:$dst), (ins GR8 :$src),
                  "movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;
After:
  def : InstAlias<"movsx $src, $dst",
                  (MOVSX16rr8W GR16:$dst, GR8:$src)>;

This also makes the alias mechanism more general and powerful, which will
be exploited in subsequent patches.

6c1b802673 Introduce DIBuilder. It is intended to be a front-end friendly interface to emit debuggging information entries in LLVM IR. 
To create debugging information for a pointer, using DIBUilder front-end just needs
	DBuilder.CreatePointerType(Ty, Size);
instead of
	DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type,
                                       TheCU, "", getOrCreateMainFile(),
                                       0, Size, 0, 0, 0, OCTy);

3bf2a701a5 In the calling convention logic, ValVT is always a legal type, 
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

f6e5e02c9b Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

67db408634 Two sets of changes. Sorry they are intermingled. 
1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to
   "optimize for latency". Call instructions don't have the right latency and
   this is more likely to use introduce spills.
2. Fix if-converter cost function. For ARM, it should use instruction latencies,
   not # of micro-ops since multi-latency instructions is completely executed
   even when the predicate is false. Also, some instruction will be "slower"
   when they are predicated due to the register def becoming implicit input.
