Removing the unaligned load tests from builtins-x86.c since they're generated by a regular 'load' now.

From Vassil Vassilev: Give external source's last resort lookup a chance, even if an identifier could resolve to a builtin.

evaluated and unevaluated contexts. Add some testing of sizeof and
typeid.

Both of the typeid tests added here were triggering warnings previously.
Now the one false positive is suppressed without suppressing the warning
on actually buggy code.

take it!

I wasn't able to get __builtin_ia32_loaddqu to transform into an unaligned
load...I'll have to look into it further.

In Microsoft mode, within class scope, if a CXXScopeSpec's type is equal to the type of one of the base classes then downgrade the missing typename error to a warning. Up to now this is the only case I found where MSVC doesn't require "typename" at class scope. Really strange!
This fixes 1 error when parsing the MSVC 2008 header files.
Example:

template<class T> class A {
public:
  typedef int TYPE;
};
template<class T> class B : public A<T> {
public:
  A<T>::TYPE a; // no typename required because A<T> is a base class.
};

there is no reason to align them higher.
 - This roughly matches llvm-gcc's r126913.
 - It is an open question whether or not we should do this for cstring's in
   general (code size vs optimization potential), for now we just match llvm-gcc
   until someone wants to run some experiments.

because the result is ignored.  The particular example here is with
property l-values, but there could be all sorts of lovely casts that this
isn't safe for.  Sink the check into the one case that seems to actually
be capable of honoring this.

ArrayBoundCheckerV2: don't arbitrarily warn about indexing before the 0-index of a symbolic region.  In many cases that isn't really the base offset.

This patch adds modeling of strcmp() to the CString checker. Validates inputs are not NULL and are real C strings, then does the comparison and binds the proper return value. Unit tests included.

for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.
