InferAddressSpaces does not check address space in collectFlatAddressExpressions,
which causes values with non flat address space put into Postorder and causes
assertion in cloneValueWithNewAddressSpace.
This patch fixes assertion in OpenCL 2.0 conformance test generic_address_space
subtest for amdgcn target.

Eliminates some more cases where some subset of the addressing
computation remains flat. Some cases with addrspacecasts
in nested constant expressions are still left behind however.

Fixes leaving intermediate flat addressing computations
where a GEP instruction's source is a constant expression.
Still leaves behind a trivial addrspacecast + gep pair that
instcombine is able to handle, which ideally could be folded
here directly.

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

This adds a parameter to @llvm.objectsize that makes it return
conservative values if it's given null.
This fixes PR23277.

For now just port some of the existing NVPTX tests
and from an old HSAIL optimization pass which
approximately did the same thing.
Don't enable the pass yet until more testing is done.
