now SymbolicNonLValue.

Cleaned up some casts.

llvm-svn: 46467

Renamed ExprValue to RValue, as all expression values are RValues, and this
keeps with the C terminology (renamed old "RValue" class to "NonLValue").

Introduced "ConcreteInt", a class that represents a concrete, integer
constant as an RValue.

Temporarily removed classes to represent set of possible constants and set of !=
constants. Will replace with a more general class representing a set of
constraints.

Added some foundational code to track "symbolic" values, which are used to
accrue constraints on an abstract value that is shared between multiple
variables.  e.g:

   x = y;      // at this point "x" and "y" share the same "value"
   if (x > 1) 
     ...       // at this point, the value shared by "x" and "y" is "> 1".

Add -Wno-rewrite-macros to silence the following warning when using -rewrite-test:

xx.m:10:3: warning: rewriting sub-expression within a macro (may not be correct)

Fix a bug with struct initializers (in Sema::CheckInitializerListTypes()). 
Test case included from bz1948 (thanks Neil!).
Also fixed an 80 column violation...

Added back logic in patch r46361 (http://llvm.org/viewvc/llvm-project?rev=46361&view=rev) with the addition of
some previously missing NULL pointer checks.

Modified the UninitializedValues analysis to not expect that every Expr* at the
block-level is a block-level expression (we probably need to change the name of
such expressions to something truer to their meaning).

Renamed RValueConjunctiveUnequal to RValInequalityANDSet.

Refactored add/subtract/multiple (and now divide) operations for
RValEqualityORSet to be based on a single template function.

Replace Sema::CheckVariableInitList, CheckConstantInitList, and CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers.

This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)

Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)

information is not separated into a "base" and "sub" type. Eventually the
value-tracking logic will know about LValues and RValues, but not about
specialized LValues and RValues; separating the "kind" information into bits
indicating whether an ExprValue is an LValue or an RValue from the bits that
specify the actual value type makes this separation easier.

a Stmt* is a block-level expression when we INSERT a value into the map, and
not also when we QUERY a value.
