Major cleanup of path-sensitive analysis engine and the current analysis
...
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.

Added classes SolarisTargetInfo and

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.
