AMDGPU: Remove disable-irstructurizer subtarget feature The only real reason to use it is for testing, so replace it with a command line option instead of a potentially function dependent feature. llvm-svn: 273653

; These tests make sure the compiler is optimizing branches using predicates
; when it is legal to do so.

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
