Avoids a couple of copies and allows more flexibility in the clients.

SLPVectorizer: Reduce the compile time by eliminating the search for some of the more expensive patterns. After this change will only check basic arithmetic trees that start at cmpinstr.

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).

llvm-svn: 179925

Allow tail call opportunity detection through nested and/or multiple iterations of extractelement/insertelement indirection

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).

trying to move as much FastISel logic as possible out of the main path in
SelectionDAGISel - intermixing them just adds confusion.

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.

This checks the sanity of the register use lists in the MI intermediate
representation.

Based on the patch by David Nadlinger!

Also make some static function class functions to avoid having to mention the
class namespace for enums all the time.

No functionality change intended.

Thanks to Evgeniy Stepanov for reporting this.

It might be a good idea to add a command iterator abstraction to MachO.h, but
this fixes the bug for now.
