[CUDA] Split device-var-init.cu tests into separate Sema and CodeGen parts. Codegen tests for device-side variable initialization are subset of test cases used to verify Sema's part of the job. Including CodeGenCUDA/device-var-init.cu from SemaCUDA makes it easier to keep both sides in sync. Differential Revision: http://reviews.llvm.org/D20139 llvm-svn: 270107

// REQUIRES: nvptx-registered-target
// Make sure we don't allow dynamic initialization for device
// variables, but accept empty constructors allowed by CUDA.
Avoid depending on test inputes that aren't in Inputs Some people have weird CI systems that run each test subdirectory independently without access to other parallel trees. Unfortunately, this means we have to suffer some duplication until Art can sort out how to share these types. llvm-svn: 270164

[CUDA] Rework tests now that we emit deferred diagnostics during sema. Test-only change. Summary: Previously we had to split out a lot of our tests into a test that checked only immediate errors and a test that checked only deferred errors. This was because, if you emitted any immediate errors, we wouldn't run codegen, where the deferred errors were emitted. We've fixed this, and now emit deferred errors during sema. This lets us merge a bunch of tests, and lets us convert some other tests to -fsyntax-only.
