Revert "intmax_t is long long on Darwin, not long."

'long' and 'long long' are different for the purposes of mangling.
This caused <rdar://problem/13254874>.

This reverts commit c2f994d31ec85e9af811af38eb1b28709aef0b2c.

Doxycomment SVal's getAs/castAs.

Also document TypeLoc's operations similarly, since it's a good idea.

objective-C arc IR-gen. Retaining of strong
arguments in function prologue is done
with objc_StoreStrong to pair it with
similar objc_StoreStrong for release in function
epilogue. This is done with -O0 only.

Strip 'llvm' from 'llvm::Optional' uses.

[analyzer] Tighten up safety in the use of lazy bindings.

- When deciding if we can reuse a lazy binding, make sure to check if there
  are additional bindings in the sub-region.
- When reading from a lazy binding, don't accidentally strip off casts or
  base object regions. This slows down lazy binding reading a bit but is
  necessary for type sanity when treating one class as another.

A bit of minor refactoring allowed these two checks to be unified in a nice
early-return-using helper function.

Rename TypeLoc's isType to isKind

Matches changes made to SVal's similar functions based on Jordan Rose's review
feedback to r175594.

Also change isKind to take a reference rather than a non-null pointer, while I'm
at it. (& make TypeLoc::isKind private)

Use None rather than Optional<T>() where possible.

libstdc++'s <cstdalign> #includes <stdalign.h> and expects it to guard against
being included in C++. Don't define alignof or alignas in this case. Note that
the C++11 standard is broken in various ways here (it refers to the contents
of <stdalign.h> in C99, where that header did not exist, and doesn't mention
the alignas macro at all), but we do our best to do what it intended.

[analyzer] Tidy up a few uses of Optional in RegionStore.

Some that I just added needed conversion to use 'None', others looked
better using Optional<SVal>::create.

No functionality change.

[analyzer] Add another reinterpret_cast behavior test.

The test is similar to <rdar://problem/13239840> but doesn't actually test
the case that fails there. It's still a good test, though.

[analyzer] Record whether a base object region represents a virtual base.

This allows MemRegion and MemRegionManager to avoid asking over and over
again whether an class is a virtual base or a non-virtual base.

Minor optimization/cleanup; no functionality change.

Avoid implicit conversions of Optional<T> to bool.
