RewriteObjC::RewriteBlockDeclRefExpr(): Add parens to enforce precedence. This fixes <rdar://problem/6529468> clang ObjC rewriter: Need parenthesis around dereferences in rewritten Blocks.

Also changed RewriteObjC::SynthesizeBlockFunc() to declare a pointer to the block argument even when there are no user-supplied arguments to the block.

Made the common case of default address space directive as non-virtual for performance reasons. Provide a single virtual interface for directives of all sizes in  non-default address spaces.

Teach LowerBRCOND to recognize (xor (setcc x), 1). The xor inverts the condition. It's normally transformed by the dag combiner, unless the condition is set by a arithmetic op with overflow.

eliminate the legacy getIntegerVTBitMask and
getIntegerVTSignBit methods, which returned their
value as a uint64_t, so couldn't handle huge types.

turn icmp eq a+x, b+x into icmp eq a, b if a+x or b+x has other uses. This
may have been increasing register pressure leading to the bzip2 slowdown.

improvements to the EvaluateInDifferentType code.  This code works 
by just inserted a bunch of new code and then seeing if it is 
useful.  Instcombine is not allowed to do this: it can only insert
new code if it is useful, and only when it is converging to a more
canonical fixed point.  Now that we iterate when DCE makes progress,
this causes an infinite loop when the code ends up not being used.
