This is a temporary solution to avoid running out of file descriptors (which defaults to 256).

Need to benchmark to understand the speed benefit. If the benefit is small, the simple solution is to avoid memory mapping files. If the benefit is significant, more thought is necessary.

GRSimpleVals.h

Added a PathDiagnosticClient option to the driver functions for the
CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o"
argument from the driver that specifies where HTML reports should be dumped.

internally in the Diagnostic object.

The support for remat of instructions with a register operand is hackish, to say the least. Since the register operand guaranteed to be PIC base and that it is already live at all uses, we are making sure it will not be spilled after its uses are rematerialized for both performance and correctness reasons.

realazthat in #llvm was having problems building llvm
because configure was finding an ocaml executable in
a directory with a space in it's name. This patch
puts quotes around the name so that llvm can build for
him.

Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
   all parent class ivars) and flattens classes.  If A derives from B, 
   and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

when something changes, instead of moving forward.  This allows us to 
simplify memset lowering, inserting the memset at the end of the range of 
stuff we're touching instead of at the start.

This, in turn, allows us to make use of the addressing instructions already
used in the function instead of inserting our own.  For example, we now
codegen:

	%tmp41 = getelementptr [8 x i8]* %ref_idx, i32 0, i32 0		; <i8*> [#uses=2]
	call void @llvm.memset.i64( i8* %tmp41, i8 -1, i64 8, i32 1 )

instead of:

	%tmp20 = getelementptr [8 x i8]* %ref_idx, i32 0, i32 7		; <i8*> [#uses=1]
	%ptroffset = getelementptr i8* %tmp20, i64 -7		; <i8*> [#uses=1]
	call void @llvm.memset.i64( i8* %ptroffset, i8 -1, i64 8, i32 1 )
