Marek Olsak c0021e43ea R600/SI: Enable a lot of existing tests for VI (squashed commits)
This is a union of these commits:

* R600/SI: Enable more tests for VI which need no changes

* R600/SI: Enable V_BCNT tests for VI
    Differences:
    - v_bcnt_..._e32 -> _e64
    - s_load_dword* inline offset is in bytes instead of dwords

* R600/SI: Enable all tests for VI which use S_LOAD_DWORD
    The inline offset is changed from dwords to bytes.

* R600/SI: Enable LDS tests for VI
    Differences:
    - the s_load_dword inline offset changed from dwords to bytes
    - the tests checked very little on CI, so they have been fixed to check all
      instructions that "SI" checked

* R600/SI: Enable lshr tests for VI

* R600/SI: Fix divrem64 tests
    - "v_lshl_64" was missing "b" before "64"
    - added VI-NOT checks

* R600/SI: Enable the SI.tid test for VI

* R600/SI: Enable the frem test for VI
    Also, the frem_f64 checking is added for CI-VI.

* R600/SI: Add VI tests for rsq.clamped
