AMDGPU: Fix test not actually testing anything It wasn't actually running the pass, and since it is missing the llvm prefix, the eh intrinsic was not really an IntrinsicInst. Also add missing test for lifetime markers. llvm-svn: 275370

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel 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). llvm-svn: 298444
