AMDGPU: Fix default device handling When no device name is specified, default to kaveri for HSA since SI is not supported and it woud fail. Default to "tahiti" instead of "SI" since these are effectively the same, and tahiti is an actual device. Move default device handling to the TargetMachine rather than the AMDGPUSubtarget. The module ISA version is computed from the device name provided with the target machine, so the attributes printed by the AsmPrinter were inconsistent with those computed in the subtarget. Also remove DevName field from subtarget since it's redundant with getCPU() in the superclass. llvm-svn: 258901

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
