DAG->DAG instruction selection for ia64! "hello world" works, not much else.
...
use -enable-ia64-dag-isel to turn this on
TODO: delete lowering stuff from the pattern isel
: get operations on predicate bits working
: get other bits of pseudocode going
: use sampo's mulh/mull-using divide-by-constant magic
: *so* many patterns ("extr", "tbit" and "dep" will be fun :)
: add FP
: add a JIT!
: get it working 100%
in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.
OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.

SparcV9 JIT.
2. Make LLVMTransformUtils a relinked object file and always link it before
LLVMAnalysis.a. These two libraries have circular dependencies on each
other which creates problem when building the SparcV9 JIT. This change
fixes the dependency on all platforms problems with a minimum of fuss.

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

allow this if the xform is strictly increasing the alignment of the
allocation.
