AMDGPU/SI: Give up in promote alloca when a pointer may be captured. Differential Revision: http://reviews.llvm.org/D28970 Reviewer: Matt llvm-svn: 292966

; Nothing should be done if the addrspacecast is captured.

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
