[analyzer] Enable destructor inlining by default (c++-inlining=destructors).

This turns on not only destructor inlining, but inlining of constructors
for types with non-trivial destructors. Per r178516, we will still not
inline the constructor or destructor of anything that looks like a
container unless the analyzer-config option 'c++-container-inlining' is
set to 'true'.

In addition to the more precise path-sensitive model, this allows us to
catch simple smart pointer issues:

  #include <memory>

  void test() {
    std::auto_ptr<int> releaser(new int[4]);
  } // memory allocated with 'new[]' should not be deleted with 'delete'

[analyzer] Reduced the unwanted correlations between checkers living inside MallocChecker.cpp

This fixes an issue pointed to by Jordan: if unix.Malloc and unix.MismatchedDeallocator are both on, then we end up still tracking leaks of memory allocated by new.
Moved the guards right before emitting the bug reports to unify and simplify the logic of handling of multiple checkers. Now all the checkers perform their checks regardless of if they were enabled, or not, and it is decided just before the emitting of the report, if it should be emitted. (idea from Anna).

Additional changes: 
improved test coverage for checker correlations;
refactoring: BadDealloc -> MismatchedDealloc

Add support for __GCC_HAVE_SYNC_COMPARE_AND_SWAP_{1,2,4,8} on x86.

This fixes std::thread with libstdc++.
