3f05a5e0ad R600/SI: Use V_FRACT_F64 for faster 64-bit floor on SI
Other f64 opcodes not supported on SI can be lowered in a similar way.

v2: use complex VOP3 patterns

59a5e979b5 R600/SI: Allow commuting compares
This enables very common cases to switch to the
smaller encoding.

All of the standard LLVM canonicalizations of comparisons
are the opposite of what we want. Compares with constants
are moved to the RHS, but the first operand can be an inline
immediate, literal constant, or SGPR using the 32-bit VOPC
encoding.

There are additional bad canonicalizations that should
also be fixed, such as canonicalizing ge x, k to gt x, (k + 1)
if this makes k no longer an inline immediate value.

d14e5ec25d R600/SI: Minor test scheduling fixes
This prevents these from failing in a later commit.

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

51a3c27d6e R600/SI: Define a schedule model and enable the generic machine scheduler
The schedule model is not complete yet, and could be improved.

b2bb846f17 R600: Clean up floor tests
These were using different naming schemes,
not using multiple check prefixes and not using
-LABEL.
