Add support for m[ft][di]bat[ul] instructions.

[X86] Place parentheses around "isMask_32(STReturns) && N <= 2".

This corrects r214672, which was committed to silence a gcc warning.

Refactor SPRG instructions.

Path: Stop claiming path::const_iterator is bidirectional

path::const_iterator claims that it's a bidirectional iterator, but it
doesn't satisfy all of the contracts for a bidirectional iterator.
For example, n3376 24.2.5 p6 says "If a and b are both dereferenceable,
then a == b if and only if *a and *b are bound to the same object",
but this doesn't work with how we stash and recreate Components.

This means that our use of reverse_iterator on this type is invalid
and leads to many of the valgrind errors we're hitting, as explained
by Tilmann Scheller here:

    http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140728/228654.html

Instead, we admit that path::const_iterator is only an input_iterator,
and implement a second input_iterator for path::reverse_iterator (by
changing const_iterator::operator-- to reverse_iterator::operator++).
All of the uses of this just traverse once over the path in one
direction or the other anyway.

Move the R600 intrinsic support back to the target machine - there's
nothing subtarget dependent about the intrinsic support in any
backend as far as I can tell.
