different from the clang type's alignment.
Summary:
Before this patch, we computed the offsets in memory of args passed to
GPU kernel functions by throwing all of the args into an LLVM struct.
clang emits packed llvm structs basically whenever it feels like it, and
packed structs have alignment 1. So we cannot rely on the llvm type's
alignment matching the C++ type's alignment.
This patch fixes our codegen so we always respect the clang types'
alignments.

Summary:
We can't do the right thing, since there's no right thing to do, but at
least we can not crash the compiler.

Summary:
This is necessary to prevent llvm from generating stacksave intrinsics
around this alloca. NVVM doesn't have a stack, and we don't handle said
intrinsics.

Summary:
The code in CGCUDACall is largely based on a patch written by Eli
Bendersky:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20140324/210218.html
That patch implemented an LLVM pass lowering printf to vprintf; this
one does something similar, but in Clang codegen.
