AMDGPU: Always allocate emergency stack slot at offset 0 This allows us to ensure that 0 is never a valid pointer to a user object, and ensures that the offset is always legal without needing a register to access it. This comes at the cost of usable offsets and wasted stack space. llvm-svn: 295877

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
