Handle allocations that, even after removing dead uses, still have more than
one use (but one is a cast).  This handles the very common case of:

 X = alloc [n x byte]
 Y = cast X to somethingbetter
 seteq X, null

In order to avoid infinite looping when there are multiple casts, we only
allow this if the xform is strictly increasing the alignment of the
allocation.

Fix a bug where we would 'promote' an allocation from one type to another
where the second has less alignment required.  If we had explicit alignment
support in the IR, we could handle this case, but we can't until we do.

Before promoting a malloc type, remove dead uses.  This makes instcombine

When a function takes a variable number of pointer arguments, with a zero
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

This file is entirely ifdef'd out

BuildSDIV and BuildUDIV only work for i32/i64, but they don't check that
the input is that type, this caused a failure on gs on X86 last night.
Move the hard checks into Build[US]Div since that is where decisions like
this should be made.

Add g3 back to the mix and reorder to irritate them anal folk.  Actually, it's
to group appropriately and provide cues to maintainers that the lists don't
need to be ordered.

Sort the features and processor lists for the sake of search (and maintainers.)

64-bit reg support should not be enabled by default, as support isn't complete.

add a case missing from the dag combiner that exposed the failure on
2005-10-21-longlonggtu.ll.

Instead of aborting if not a case we can handle specially, break out and
let the generic code handle it.  This fixes CodeGen/Generic/2005-10-21-longlonggtu.ll on ppc.

also, reindent this code
