side-effects up front, as when we switch to the llvm intrinsic call
for __builtin_object_size later, it will have two evaluations.

We also finish off the intrinsic version of the code so we can just
turn it on once llvm has the intrinsic.

someone will add an llvm intrinsic for us to use, so the optimizer can
figure out the hard cases.  WIP.

For those that want to help, double check with Eric before starting.
He has a bit of code this will plug into.

The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

Also, committing an #if 0'ed __builtin_setjmp and __builtin_longjmp 
implementation I've had sitting in my tree for a while.  I haven't 
enabled it because the LLVM backend support isn't complete yet.

semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)

Add a destination type argument to EmitConstantExpr. This will be used for when the destination has a reference type. (No functionality change yet)
