Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach
a set of provided nodes.
Fixed subtle bug in ExplodedNodeImpl where we could create predecessor
iterators that included the mangled "sink" bit. The better fix is to integrate
this bit into the void* for the wrapped State, not the NodeGroups representing
a node's predecessors and successors.

Remove the first layer of support for "portability" warnings. This is
...
theoretically useful, but not useful in practice. It adds a bunch of
complexity, and not much value. It's best to nuke it. One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay). Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.
Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed. Please poke at it when you have
time.

Two more Windows-related fixes:

- More enum signeness bitfield fixes (MSVC treats enums as signed).
- Fixed in Lex/HeaderSearch.cpp an unsafe copy between two
HeaderSearch::PerFileInfo entries in a common vector. The copy involved two
calls to getFileInfo() within the assignment; these calls could have
side-effects that enlarged the internal vector, and with MSVC this would
invalidate one of the values in the assignment.

Patch from Argiris Kirtzidis:
...
The patch fixes some debug assertions that the msvcrt throws:
1)
- if (isprint(value) && value < 256) {
+ if (value < 256 && isprint(value)) {
isprint() does an assertion check of its own for value < 256; check value before calling it to prevent it.
2)
- Stmt->Names.push_back(std::string(&data[0], data.size()));
+ if (data.size() == 0)
+ Stmt->Names.push_back(std::string());
+ else
+ Stmt->Names.push_back(std::string(&data[0], data.size()));
If data.size() == 0 then data[0] throws "out of range" assertion.

When creating the CFGBlocks for a switch statement, we now have the "default"
...
branch ALWAYS be the last successor for a switch-terminated block. This allows
clients to distinguish cases like the following:
switch(...)
case XXX:
switch(...) {
case YYY: ...
}
case ZZZ: ..
}
In this case, the block with "case ZZZ:" is the default block for the inner
switch statement, but that case is associated with the outer switch statement,
and not the inner one. Clients can test for this behavior by checking if a
successor block is the last one (and thus just assume that this is the "default"
case).
