Chris Lattner 46705b2f2d 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.

Chris Lattner 355ecc09f8 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.

Chris Lattner ac87beb03a Before promoting a malloc type, remove dead uses. This makes instcombine 
more effective at promoting these allocations, catching them earlier in the
compile process.

in the future, remove it.

Jeff Cohen 11e26b52b2 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.

Chris Lattner 9faa5b7a9a 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.

Chris Lattner e296949fbe 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
