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.

We really should not have this version number in  SO many makefiles. This should also probably change to svn instead of cvs, but leaving it for now.

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.
