instead of with mmx registers.  This horribleness is apparently
done by gcc to avoid having to insert emms in places that really 
should have it.  This is the second half of rdar://5741668.

GCC apparently does this, and code depends on not having to do
emms when this happens.  This is x86-64 only so far, second half
should handle x86-32.

any, we force sdisel to do all regalloc for an asm.  This
leads to gross but correct codegen.

based on constant. prop. and limited symbolics.

- Renamed class: RValue -> RVal, LValue -> LVal, etc.
- Minor method renamings and interface cleanups.
- Tightened the RVal "type system" so that UninitializedVal and UnknownVal
  cannot be cast to LVal or NonLVal.  This forces these corner cases values
  to be explicitly handled early before being dispatched to plug-in transfer
  function logic.
- Major cleanup in the transfer function logic for binary and unary operators.
  Still fixing some regressions, but we now explicitly handle Uninitialized
  and Unknown values in a more rigorous way.

invlolving implicit casts that cause both a decay to pointer type and a 
type conversion.

ahtough I had the fix in my tree previously.

because silly gcc 3.4.6 barfs on this
construct.
Type.h defines an "enum TQ", which makes
the parser to err.

SolarisSparcV8TargetInfo to be able
to handle "sparc-" triple prefixes.

Please be aware that this is a minimal
kludge, that pretty much duplicates
the features of DarwinPowerPCTargetInfo,
and also incorrectly uses stuff from
the PPC namespace.

But in result "make test" now passes
a lot of tests, the notable exceptions
being the objc rewrite tests and
mandel.c.
