No need to append extra padding now that we don't create packed structs for simple cases like the constant string.

AddInitializerToDecl can't take a FullExprArg. Make it take an ExprArg, and create the CXXExprWithTemporaries before setting the initializer on the VarDecl.

unfoldable references to a PHI node in the block being folded, and disable
the transformation in that case.  The correct transformation of such PHI
nodes depends on whether BB dominates Succ, and dominance is expensive 
to compute here.  (Alternatively, it's possible to check whether any 
uses are live, but that's also essentially a dominance calculation. 
Another alternative is to use reg2mem, but it probably isn't a good idea to
use that in simplifycfg.)

Also, remove some incorrect code from CanPropagatePredecessorsForPHIs 
which is made unnecessary with this patch: it didn't consider the case 
where a PHI node in BB has multiple uses.

where 'new' is coming out of the MCInst version of the printer.

Move builtin call checking out into a separate function, make CheckFunctionCall and CheckBlockCall return bool instead. No intended functionality change.

what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.

I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)
