Duncan Sands 38ef3a8ec7 Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

Fariborz Jahanian 9e7b848ac8 Added support for messagings which return a structure-value. 
(Also fixed a regression caused by recent changes to synthesis of structs).

Ted Kremenek d85026d925 Added getTrueExpr() and getFalseExpr() to ConditionalOperator. These methods 
provide handy accessors to the subexpressions of ConditionalOperator that
automatically take into account the GCC extension where the "LHS" expression is
omitted: e.g x ?: y;. When the LHS expression is available, getTrueExpr() is the
same as getLHS(); when LHS is NULL, getTrueExpr() returns the condition expression.

Chris Lattner e6535cfdd2 add support for custom client-specific diagnostics. As a testcase, make the 
rewriter emit this error if it fails to rewrite an @encode:

t.m:17:9: error: rewriter could not replace sub-expression due to macros
    c = ENC(char *)[2] + 4;

among other things.

Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables. 
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.
