* save an example for __bf16 type

* temp save, waiting for debug

* tempsave, fmha_decode

* temp save, change all instance to 1wave

* fix async copytest bug

* Add block_sync_lds_direct_load utility

* fix the s_waitcnt_imm calculation

* Improve s_waitcnt_imm calculation

* fix vmcnt shift

* tempsave. asynccopy+trload sanity checked

* remove unnecessary features

* fix the lds alignment caused performance regression

* enable prefill overload operator().

* remove all lds bankconflict with xor layouts

* enable larger tile size; upgrade xor pattern

* upgrade prefill pipeline; simple iglp; consistent data produce and consume order

* small refactor

* Load Q through lds, implement xor;

* add vmcnt guard before load ktile

* Add v_permlaneb32 for block_reduce. Disable it as it will cause un-coexecutable packed math in FA

* Add XOR fold strategy for hdim<128, but perf dropped; disable it by default; wait further perf debug

* add __restrict__ to tr load

* merge fa_decode pipeline into fmha_fwd api

* remove unnecessary files; rename some files

* Remove unnecessary changes

* bug fix, clang format;

* remove non-necessary change

* fix clangformat with 18.1.3
