Matt Arsenault 3dbeefa978 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).

Matt Arsenault f8fb605a68 AMDGPU: Fix asserting on 0 dmask for image intrinsics

Changpeng Fang 8236fe103f AMDGPU/SI: Support data types other than V4f32 in image intrinsics
Summary:
  Extend image intrinsics to support data types of V1F32 and V2F32.

  TODO: we should define a mapping table to change the opcode for data type of V2F32 but just one channel is active,
  even though such case should be very rare.

Changpeng Fang fb9c3818dd AMDGPU/SI: Implement amdgcn image intrinsics with sampler
Summary:
  This patch define and implement amdgcn image intrinsics with sampler.

    1. define vdata type to be llvm_anyfloat_ty, address type to be llvm_anyfloat_ty,
       and rsrc type to be llvm_anyint_ty. As a result, we expect the intrinsics name
       to have three suffixes to overload each of these three types;

    2. D128 as well as two other flags are implied in the three types, for example,
       if you use v8i32 as resource type, then r128 is 0!

    3. don't expose TFE flag, and other flags are exposed in the instruction order:
       unrm, glc, slc, lwe and da.
