Summary:
Calling any non-libc builtin function in the expression command currently just causes Clang
to state that the function is not known. The reason for this is that we actually never
initialize the list of builtin functions in the Builtin::Context.
This patch just calls the initializer for the builtins in the preprocessor. Also adds some tests
for the new builtins.
It also gets rid of the extra list of builtins in the ClangExpressionParser, as we can just reuse
the existing list in the Preprocessor for the ASTContext. Having just one list of builtins around
is also closer to the standard Clang behavior.

Summary:
There is currently a way to skip the debugserver build. See how the CMake
variables SKIP_DEBUGSERVER and LLDB_CODESIGN_IDENTITY are used if you're
interested in that.
This allows us to skip building lldb-server as well. There is another
debug server called ds2 that can be used with LLDB. If you choose to use
ds2, this flag is very useful because it can cut down the build time of LLDB.

With this patch, users can now customize the pipeline selection strategy for
scheduler resources. The resource selection strategy can be defined at processor
resource granularity. This enables the definition of different strategies for
different hardware schedulers.
To override the strategy associated with a processor resource, users can call
method ResourceManager::setCustomStrategy(), and pass a 'ResourceStrategy'
object in input.
Class ResourceStrategy is an abstract class which declares virtual method
`ResourceStrategy::select()`. Method select() is meant to implement the actual
strategy; it is responsible for picking the next best resource from a set of
available pipeline resources. Custom strategy must simply override that method.
By default, processor resources are associated with instances of
'DefaultResourceStrategy'. A 'DefaultResourceStrategy' internally implements a
simple round-robin selector. For more details, please refer to the code comments
in Scheduler.h.

Summary:
This patch implements a new cache for the result of SMT queries; with this patch the regression tests are 25% faster.
It's implemented as a `llvm::DenseMap` where the key is the hash of the set of the constraints in a state.
There is still one method that does not use the cache, `getSymVal`, because it needs to get a symbol interpretation from the SMT, which is not cached yet.

Summary:
With this patch, the SMT backend is almost completely detached from the CSA.
Unfortunate consequence is that we missed the `ConditionTruthVal` from the CSA and had to use `Optional<bool>`.
The Z3 solver implementation is still in the same file as the `Z3ConstraintManager`, in `lib/StaticAnalyzer/Core/Z3ConstraintManager.cpp` though, but except for that, the SMT API can be moved to anywhere in the codebase.

Summary:
By making SMTConstraintManager a template and passing the SMT constraint type and expr, we can further move code from the Z3ConstraintManager class to the generic SMT constraint Manager.
Now, each SMT specific constraint manager only needs to implement the method `bool canReasonAbout(SVal X) const`.
