1) objc ivar processing is split out of ActOnField into its own ActOnIvar method.
2) the new objc ivar action takes visibility info directly, eliminating 
  AllVisibilities in ParseObjCClassInstanceVariables.

in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment
as a ComputeMaskedBits problem, moving all of its special alignment
knowledge to ComputeMaskedBits as low-zero-bits knowledge.

Also, teach ComputeMaskedBits a few basic things about Mul and PHI
instructions.

This improves ComputeMaskedBits-based simplifications in a few cases,
but more noticeably it significantly improves instcombine's alignment
detection for loads, stores, and memory intrinsics.

declarators.  This allows the clients (C structs, objc classes, objc 
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating 
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

how to do that safely.  Thoughts welcome.
