exception handling table if we encounter it multiple
times.  Filters could be folded harder than this, but
that would mean a lot more work for not much gain.

Each ARM use predicate operand is now made up of two components. The new component is the CPSR register.

- Added two variants of PredicateOperand: ImmutablePredicateOperand, whose predicate does not change after isel; PredicateDefOperand, which represent a predicate defintion operand.

Add functionality to value number GEP instructions.  This also provides the infrastructure that will
be used for function calls.  NOTE: This does not yet do any transformation of GEPs or function calls.

the recent lowering changes, this allows types like <4 x double> to
be returned, using two vector registers.

refactored getCopyFromParts and getCopyToParts, which are more general.
This effectively adds support for lowering illegal by-val vector call
arguments.

visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG
to use isNegatibleForFree/GetNegatedExpression instead of doing a subset
of the same thing manually.

This fixes test/CodeGen/X86/negative-sin.ll.
