Steve Naroff ddb1dd8c5f Tighten up ASTContext::typesAreCompatible()...it needs to make sure the qualifiers match. The comment and C99 citation for this routine were correct...the code needed to conform to the comment/spec. This fixes the test added below.
Tightening up this routine forced tweaks to Sema::CheckSubtractionOperands() and Sema::CheckCompareOperands(). For example, they both need to operate on the unqualified pointee...

for analyzing a function.

The initial state for GRConstants now assigns symbolic values to parameters.

Ted Kremenek 8ff7705a6c Modified LiveVariables to perform all of its base initialization in the ctor,
and now we require a FunctionDecl* object so that we can also keep track of
all of the ParmDecls.

Scott Michel 167502a508 Fix to bug 1951: tblgen gratuitously renames variables when no temporary was
generated. This feature would only show up in fairly complex patterns, such
as this one in CellSPU:

  def : Pat<(add (SPUhi tconstpool:$in, 0), (SPUlo tconstpool:$in, 0)),
	    (IOHLlo (ILHUhi tconstpool:$in), tconstpool:$in)>;

which generated the following emit code:

SDNode *Emit_0(const SDOperand &N, unsigned Opc0, unsigned Opc1, MVT::ValueType VT0, MVT::ValueType VT1) DISABLE_INLINE {
  SDOperand N0 = N.getOperand(0);
  SDOperand N00 = N0.getOperand(0);
  SDOperand N01 = N0.getOperand(1);
  SDOperand N1 = N.getOperand(1);
  SDOperand N10 = N1.getOperand(0);
  SDOperand N11 = N1.getOperand(1);
  SDOperand Tmp3(CurDAG->getTargetNode(Opc0, VT0, N00), 0);
  return CurDAG->SelectNodeTo(N.Val, Opc1, VT1, Tmp3, Tmp2); /* Tmp2 s/b N00 */
}

Tested against the test suites without incident.

Scott Michel ceae3bbf4d Overhaul Cell SPU's addressing mode internals so that there are now
only two addressing mode nodes, SPUaform and SPUindirect (vice the
three previous ones, SPUaform, SPUdform and SPUxform). This improves
code somewhat because we now avoid using reg+reg addressing when
it can be avoided. It also simplifies the address selection logic,
which was the main point for doing this.

Also, for various global variables that would be loaded using SPU's
A-form addressing, prefer D-form offs[reg] addressing, keeping the
base in a register if the variable is used more than once.

Ted Kremenek 17a739681c Some additional cleanups with method names.
Renamed ExprValue to RValue, as all expression values are RValues, and this
keeps with the C terminology (renamed old "RValue" class to "NonLValue").

Introduced "ConcreteInt", a class that represents a concrete, integer
constant as an RValue.

Temporarily removed classes to represent set of possible constants and set of !=
constants. Will replace with a more general class representing a set of
constraints.

Added some foundational code to track "symbolic" values, which are used to
accrue constraints on an abstract value that is shared between multiple
variables.  e.g:

   x = y;      // at this point "x" and "y" share the same "value"
   if (x > 1) 
     ...       // at this point, the value shared by "x" and "y" is "> 1".
