Fix TileLang ST CI failures

[mouliangyu]

Summary

• Fix TileOps lowering/runtime issues exposed by full TileLang ST, including tload/tmov-to-scale/tstore-fp scaling payloads and sync effects.
• Add focused lit coverage for MAT->scaling pipe selection and tstore_fp memory effects.
• Restore the earlier incorrect test deletion/filtering direction: final PR diff has no net changes to run_st.py, testcase CMakeLists, tcvt, or mx_fp4.py versus main. Full regression stays enabled.
• Update the acc_store vector pre_quant negative lit case so ui64 remains a valid scaling payload and ui32 is used for the invalid payload check.

Validation

• cmake --build build-main-llvm21 -j64 --target ptoas
• CI=1 PTOAS_BIN=$PWD/build-main-llvm21/tools/ptoas/ptoas bash test/tilelang_st/script/run_ci.sh -r sim -v a5 --jobs 64
  • TileLang ST summary: passed=106 failed=0 total=106
  • tcvt ran the full 251-case set; no case filtering.
• ptoas + FileCheck: test/lit/pto/tmov_m2s_pipe_selection.pto
• ptoas + FileCheck: test/lit/vpto/tstore_fp_sync_effects.pto
• ptoas + FileCheck: test/lit/vpto/acc_store_verify_invalid_pre_quant_vec_payload_type.pto

你现在在审查 GitHub PR。

仓库：hw-native-sys/PTOAS
PR：#907 Fix TileLang ST CI failures
作者：mouliangyu
base branch：origin/main
head branch：HEAD（当前已 checkout 到 PR head）

要求：
1. 只审查这个 PR 相对 origin/main 的改动，必要时可以看上下文文件。
2. 重点找真实的 correctness / regression / contract mismatch / CI / runtime / compatibility 问题。
3. 不要提纯风格建议，不要提低价值猜测。
4. 严格按优先级输出：
   - P1：高概率会导致错误结果、编译/运行失败、严重回归、发布阻断
   - P2：重要缺陷、行为回归、遗漏校验/测试、较大兼容性问题
   - P3：次要但明确可改的问题
5. 如果没有问题，summary 直接写：未检查到 PR #907 存在问题，并返回 findings=[]。
6. 如果有问题，summary 简洁概括，findings 里每条都要给出：
   - severity
   - title
   - body（说明为什么是问题，尽量具体）
   - file（尽量给相对路径）
   - line（能确定就填整数，否则 null）

建议先查看：
- git status --short
- git diff --stat origin/main...HEAD
- git diff --unified=80 origin/main...HEAD

最终输出必须严格匹配 JSON schema。
