71195650ea Add a missing Module::setTargetTriple method. 
Remove Function::aiterator and Module::giterator typedefs (and const versions)
as they should have been removed when abegin/gbegin were removed.  Thanks to
alkis for bringing this to my attn.

b299faa5c1 Move the END_WITH_NULL marker. Vladimir suggests that this works better with 
GCC 4.1.  I tried it with 4.0 and 3.3 and it seems fine.

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.

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.

ee581735d9 Add the ability to lower return instructions to TargetLowering. This 
allows us to lower legal return types to something else, to meet ABI
requirements (such as that i64 be returned in two i32 regs on Darwin/ppc).

9c069d09a5 Annotate nodes with their addresses if a graph requests it.

this behavior.  This is currently used by selection dags.

96f29dbdbe Make this slightly more efficient by pushing actual type information down 
into the evaluator.  This shrinks a release build of instcombine's text
section from 216363 to 215975 bytes (on PPC).

92616caa1a Split SimpleConstantVal up into its components, so each Constant subclass gets 
a different enum value.  This allows 'classof' for these to be really simple,
not needing to call getType() anymore.

This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
