a3aa0cf6e6 Made GetVariableValue() more robust in the face 
of failures in the AST importer.  Also ensured
that a variable will not be blindly added if
GetVariableValue() returns an error.

de2bdf637e Revert r119838 "Don't warn for empty 'if' body if there is a macro that expands to nothing" 
and use a better and more general approach, where NullStmt has a flag to indicate whether it was preceded by an empty macro.

Thanks to Abramo Bagnara for the hint!

2d107dd02b Change the DWARFExpression::Evaluate methods to take an optional 
RegisterContext* - normally this is retrieved from the ExecutionContext's
StackFrame but when we need to evaluate an expression while creating
the stack frame list this can be a little tricky.

Add DW_OP_deref_size, needed for the _sigtramp FDE expression.

Add support for processing DWARF expressions in RegisterContextLLDB.

Update callers to DWARFExpression::Evaluate.

8bf9e546d4 Detemplatize NodeRef. 
It is now possible to navigate the B+-tree using NodeRef::subtree() and
NodeRef::size() without knowing the key and value template types used in the
tree.

3864c518c2 Rename NodeBase::{key,val} as {first,second} and swap the BranchNode arrays such 
that the noderefs are the first member in the object.

This is in preparation of detemplatization of tree navigation.

dfb8c3bbfc When folding addressing modes in CodeGenPrepare, attempt to look through PHI nodes 
if all the operands of the PHI are equivalent.  This allows CodeGenPrepare to undo
unprofitable PRE transforms.

1a9ca21881 Several PPCallbacks take an SourceLocation + IdentifierInfo, rather 
than a Token that holds the same information all in one easy-to-use
package.  There's no technical reason to prefer the former -- the
information comes from a Token originally -- and it's clumsier to use,
so I've changed the code to use tokens everywhere.
