Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it.

Tests that were using it were operating as if using -emit-spirv-directly, leading to many duplicated tests. After fixing the test option, there were an number of errors that appeared as a result. This change fixes the broken test option and the resulting test errors. Some of the test errors revealed some legitimate issues, such as: -The GLSL bitCount instrinsic only supports 32-bit integers and requires emulation for other bit widths. -Emitting GLSL 8-bit and 16-bit glsl integer types did not emit the proper extension requirements -Emitting GLSL and casting for 16-bit integers was missing a closing parenthesis. -Missing profile for GL_EXT_shader_explicit_arithmetic_types -Missing toType cases for UInt8/Int8 for the kIROp_BitCast case in tryEmitInstExprImpl. 2025-05-15T02:57:47+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2025-05-15T02:57:47+00:00 urn:sha1:b4d3d3017640581c21b52a12413d3f074ab1c5c1 **NOTE: This is a breaking change for users who were using POC variant of DXC. In order to keep the compatibility, the users will have to use -capability hlsl_coopvec_poc to their command line. This PR adds a new capability "hlsl_coopvec_poc". When it is used, the HLSL for CoopVec will be emitted for the POC variant of DXC. When it is not used, the HLSL for CoopVec will be emitted for the DXC that officially supports the cooperative vector. 2025-04-16T23:14:12+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2025-04-16T23:14:12+00:00 urn:sha1:8b2327b77110b6e5955ffc7fa181091cacc5674a With this PR, cooperative-vector tests will run only when the hardware can support the feature. Unfortunately, DX12 backend will always reports that cooperative-vector is NOT supported until it is officially supported in May. 2025-04-02T20:06:45+00:00 Jay Kwak 82421531+jkwak-work@users.noreply.github.com 2025-04-02T20:06:45+00:00 urn:sha1:b4a1d618b8d850a579af2840db2df6bee312172c This PR enables existing CoopVec tests with DX12 backend. In order to use the CoopVec feature with DX12 backend, we have to use an option, "-dx12-experimental", because the current implementation of CoopVec feature in dxcompiler.dll requires "experimental feature". Note that when the "experimental feature" is enabled, slang-test becomes less stable. For that reason, we should use the option "-dx12-experimental" only when it is needed. All tests for GLSL are deleted because CoopVec support for GLSL in Slang is deprecated and no longer supported. Some of CoopVec tests are still disabled for DX12 backend because: DXC doesn't support 8bit integer types and Some of CoopVec features are not implemented in DXC backend.
