abstract "L-values" and "R-values" when doing value tracking, and expanding
constant tracking to encompass tracking disjunctive sets of possible constants.
Further, the tree-walking is more efficient, as we don't blindly recurse the
tree if we won't generate new states.

use ImmutableMap::SlimFind(), which returns the correct value.

Added pruning of dead block-level expressions and Decls from our value map
using liveness information.

values for the block-level expressions.

Modified 'LiveVariables' to provide the option to clients to record
liveness information for block-level expressions (using the above feature).

Modified 'DeadStores' to conform to the new interface of 'LiveVariables'.

Modified 'GRConstants' to compute liveness information for block-level
expressions.

Refactored the use of this method into both the Sema module and Analysis module,
which were using their own static functions that did the same thing.

Fixed some compilation errors with GREngine that showed up during
template instantiation.

node caching in GREngine will guarantee that we do not insert a node twice into
a nodeset.

variant type, and not just the pointer value.

llvm-svn: 46049

Cleaned up GRConstants::AddBinding to not directly reference the
predecessor node.  Now we just manipulate the current state, and a driver
function creates nodes as needed.
