a38c737e85 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.

d308f398c0 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.

12484c7699 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.

ffa76df587 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

5a9eb6d07b Make the coallescer a bit smarter, allowing it to join more live ranges. 
For example, we can now join things like [0-30:0)[31-40:1)[52-59:2)
with [40:60:0) if the 52-59 range is defined by a copy from the 40-60 range.
The resultant range ends up being [0-30:0)[31-60:1).

This fires a lot through-out the test suite (e.g. shrinking bc from
19492 -> 18509 machineinstrs) though most gains are smaller (e.g. about
50 copies eliminated from crafty).

393200c3c6 Fix LiveInterval::getOverlapingRanges to take things in the right order 
(an unused method).

Fix the merger so that it can merge ranges like this  [10:12)[16:40) with
[12:38) into [10:40) instead of bogus ranges.  This sort of input will be
possible for the merger coming shortly

6c42f509bc Invert the TargetLowering flag that controls divide by consant expansion. 
Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.
Implement some more ISD::SDIV folds in the dag combiner
Remove now dead code in the x86 backend.
