since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.

Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

Also fix the function visitor to visit exception types in function

look into the type of "this->blah" (e.g., because it is dependent),

FP_REG_KILL instructions are still inserted, but can be disabled by passing
-live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly.

CFG edges are partioned into bundles where the x87 stack must be allocated
identically. Code is insertad at the end of each basic block that shuffles the
live FP registers to match the outgoing bundles expectations.

This fix is in preparation for some upcoming register allocator improvements
that may extend the live range of registers beyond a basic block, similar to
LICM. It also provides a nice runtime speedup if you are building with
-mfpmath=387.

handling the parsing of scanf format strings and hooking the checking into Sema.
Most of this checking logic piggybacks on what was already there for checking printf format
strings, but the checking logic has been refactored to support both.

What is left to be done is to support argument type checking in format strings and of course
fix the usual tail of bugs that will follow.

like we do with printf functions.  Follow-up work is needed to add similar support
for fscanf et al.

This is to support format-string checking for scanf functions.
