expression in IVUsers, because in the case of a use of a non-linear
addrec outside of a loop, this causes the addrec to be evaluated as
a linear addrec.

well with the existing loadpre that j-t does to open up many new jump
threads earlier.

Latency information for ARM v6. It's rough and not yet hooked up. Right now  we are only using branch latency to determine if-conversion limits.

while experimenting.  I'm reasonably sure this is correct, but please 
tell me if these instructions have some strange property which makes this
change unsafe.

implementation.  The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst.  MCInst
and the new asmprinters will not depend on most of the 
llvm code generators.  This allows building diassemblers
that don't link in the whole llvm code generator.  This is
step #1 of many.

into DarwinTargetAsmInfo.cpp.  The remaining differences should
be evaluated.  It seems strange that x86/arm has .zerofill but ppc
doesn't, etc.

On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

as signed max tests. Along with r73717, this helps CodeGen avoid
emitting code for a maximum operation for this class of loop.
