Handle global allocations for 64-bit targets
On 64-bit targets global allocations are not promoted to registers and take
memcpys instead when accessed, so the analysis in global allocation LLVM
pass is extended to handle that case. A new LIT testcase is added.
This CL also removed global allocation declarations from LLVM IR to
prevent them from showing in the result SPIR-V code, which otherwise
may crash certain Vulkan drivers.
