parameter with a default value, instead of just hardcoding it in the
implementation.  The limit of MaxLookup = 6 was introduced in r69151 to fix
a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
Making the limit part of the method signature makes it clear that by default
the result is limited and should help avoid similar problems in the future.
This fixes pr6126.

Previously we would just silently miscompile code that used aligned
common's, now at least you'll get a build error.  tiger-ppc already
triggered the build error because it didn't have a version of this
logic.

We are not emitting alignments on Darwin for "bar". Not sure what is the
correct way to do it.

It looks like linux/arm and linux/mips have the same setting, which 
are probably wrong.  Someone who cares about ARM and MIPS should 
investigate with the testcase in PR6129.

code, matches the policy for zext (cond ? 1 : 0 -> zext), and allows
us to generate better code for a testcase on ppc.

the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also,
keep track of the SDNode ordering by default. Eventually, we would like to make
this ordering a way to break a "tie" in the scheduler. However, doing that now
breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux.

However, I think that this directive should be safe on any ELF target.
If so, we should hoist it up out of the X86 and SystemZ targets.
