[analyzer] rename all experimental checker packages to have 'experimental' be the common root package.

[analyzer] Introduce MallocOverflowSecurityChecker, a simple flow-sensitive checker that may be useful for security auditing.  This checker is currently too noisy to be on by default.

KeychainAPI checker: only check the paths on which the allocator function returned noErr. (+ minor cleanup)

llvm-svn: 136694

Add a skeleton for the Keychain Services API Checker. Register it as OSX experimental for now. Note, the checker still does not handle tracking of escaped values, taking into account the return value of the allocator functions, nor the actual bug reporting..

[analyzer] CStringChecker checks functions in the C standard library, not C++. Its external name is now unix.experimental.CString.

Add an Objective-C checker that checks that arguments passed to some variadic Objective-C methods are of Objective-C pointer types.

Ted or Argiris, I'd appreciate a review!

Re-enable the IdempotentOperations checker for --analyze, and put it and the DeadStores checker into the "deadcode" group.

This checker was created by Jim Goodnow II, and I migrated it to the
new Checker interface (recent changes by Argiris).

They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.

-The driver passes the above flag by default.

For example, if 'core.experimental.UnreachableCode' is hidden, it should not be enabled with 'core.experimental'.
Note that this requires llvm commit r126436.

The relative checker package is 'debug':

'-dump-live-variables' is replaced by '-analyzer-checker=debug.DumpLiveVars'
'-cfg-view' is replaced by '-analyzer-checker=debug.ViewCFG'
'-cfg-dump' is replaced by '-analyzer-checker=debug.DumpCFG'
