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
