6183f78cf8 Add a parameter to getCopyToParts and getCopyFromParts to specify whether 
endian swapping should be done, and update the code to use it. This fixes
some register ordering issues on big-endian systems, such as PowerPC,
introduced by the recent illegal by-val arguments changes.

14da32a486 Make sure only one copy of a filter is placed in the 
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.

visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG

of the same thing manually.

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

b6f5b00c3b Add new TargetLowering code to provide the final register type that an 
illegal value type will be transformed to, for code that needs the
register type after all transformations instead of just after the first
transformation.

Factor out the code that uses this information to do copy-from-regs and
copy-to-regs for various purposes into separate functions so that they
are done consistently.
