Added implicit promotions to the transfer function logic for compound

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.

example, we can now correctly build the type for things like:
    _AS1 float * _AS2 *B;

llvm-svn: 47420

llvm-svn: 47419

allows us to correctly handle stuff like:

and to reject stuff like:

  _AS1 _AS2* x;

rename QualType::getQualifiers to getCVRQualifiers.
Add some fixme's and clean up some code relevant to qualifiers.
Change ASQualType to contain a Type* instead of a QualType.  
Any CVR qualifiers should be on the outer qual type.
