The getSwappedPredicate function can be used in other places (such as in
improvements to the PPCCTRLoops pass). Instead of trapping it as a static
function in PPCInstrInfo, move it into PPCPredicates with other
predicate-related things.

No functionality change intended.

Add CodeGen support for functions that always return arguments via a new parameter attribute 'returned', which is taken advantage of in target-independent tail call opportunity detection and in ARM call lowering (when placed on an integral first parameter).

and persistent variables so that they are not
treated as remaining in the target process (i.e.,
having live data) when the process does not allow
persistent allocations (e.g., when there is no
process or in the case of kernel core files).

Instead, use MappingNormalization to directly parse COFF::header. Also change
the naming convention of the helper classes to be a bit shorter.

Introduce a new helper function, which computes the first symbolic region in
the base region chain. The corresponding symbol has been used for assuming that
a pointer is null. Now, it will also be used for checking if it is null.

This ensures that we are tracking a null pointer correctly in the BugReporter.

The logic that actually compares the types considers pointers and integers the
same if they are of the same size. This created a strange mismatch between hash
and reality and made the test case for this fail on some platforms (yay,
test cases).

- memory.MismatchedDelete, memory.MultipleDelete, and memory.DeallocateNonPtr
  are complete (unix.MismatchedDeallocator and cplusplus.NewDelete)
- Per discussion on the mailing list, different.UnaryPlusWithUnsigned has
  dubious value; remove it.
- Add potential checker ctordtor.PlacementSelfCopy per an internal bug report.
- core.AttributeNonNull is now core.NonNullParamChecker, though no one should
  be depending on this name anyway.

When matching a compare with a subtract where the arguments of the compare are
swapped w.r.t. the arguments of the subtract, we need to negate the predicates
(or CR bit indices) of the users. This, however, is not the same as inverting
the predicate (negating LT -> GT, but inverting LT -> GE, for example). The ARM
backend seems to do this correctly, but when I adapted the code for the PPC
backend, I introduced an error in this logic.

Comparison optimization is now enabled again by default.
