It seems the hardware requires a dummy PS state with a noop FS,
otherwise it might just hang. This used to work just fine on older
gens.
Note that RadeonSI refuses to draw if VS or PS is missing and AMDVLK
seems to also always emit this state. So, this might be a bug that AMD
didn't encounter at all.
This fixes a GPU hang during loading with Ghostwire: Tokyo.

This feature bit has inverted polarity from most other feature bits:
if the bit is present the driver should not use early Z. So the bit
must be set when the debug option to disable early Z is enabled.

This change began by fixing an old regression related to the dceil
functionality. This issue affected palm. Now, this change adjusts
the software fp64 support to make it fully operational.
This change was tested on palm and barts. This change fixes 561
"piglit run all" tests. The khr_gl tests are fixed as well (243 tests).
Here is a summary:

The key change is to use a builder to write the expected shader result
and compare that. To make this less error prone, a few helper functions
were added
- a way to allocate VGRFs from both shaders in parallel, that way the
same brw_reg can be used in both of them;
- assertions that a pass will make progress or not, and proper output
when the unexpected happens;
- use a common brw_shader_pass_test class so to collect some of the helpers;
- make some helpers work directly with builder.
The idea is to improve the signal in tests, so that the disasm comments
are not necessary anymore. For example
```
TEST_F(saturate_propagation_test, basic)
{
brw_reg dst1 = bld.vgrf(BRW_TYPE_F);
brw_reg src0 = bld.vgrf(BRW_TYPE_F);
brw_reg src1 = bld.vgrf(BRW_TYPE_F);
brw_reg dst0 = bld.ADD(src0, src1);
set_saturate(true, bld.MOV(dst1, dst0));
/* = Before =
*
* 0: add(16) dst0 src0 src1
* 1: mov.sat(16) dst1 dst0
*
* = After =
* 0: add.sat(16) dst0 src0 src1
* 1: mov(16) dst1 dst0
*/
brw_calculate_cfg(*v);
bblock_t *block0 = v->cfg->blocks[0];
EXPECT_EQ(0, block0->start_ip);
EXPECT_EQ(1, block0->end_ip);
EXPECT_TRUE(saturate_propagation(v));
EXPECT_EQ(0, block0->start_ip);
EXPECT_EQ(1, block0->end_ip);
EXPECT_EQ(BRW_OPCODE_ADD, instruction(block0, 0)->opcode);
EXPECT_TRUE(instruction(block0, 0)->saturate);
EXPECT_EQ(BRW_OPCODE_MOV, instruction(block0, 1)->opcode);
EXPECT_FALSE(instruction(block0, 1)->saturate);
}
```
becomes
```
TEST_F(saturate_propagation_test, basic)
{
brw_builder bld = make_shader(MESA_SHADER_FRAGMENT, 16);
brw_builder exp = make_shader(MESA_SHADER_FRAGMENT, 16);
brw_reg dst0 = vgrf(bld, exp, BRW_TYPE_F);
brw_reg dst1 = vgrf(bld, exp, BRW_TYPE_F);
brw_reg src0 = vgrf(bld, exp, BRW_TYPE_F);
brw_reg src1 = vgrf(bld, exp, BRW_TYPE_F);
bld.ADD(dst0, src0, src1);
bld.MOV(dst1, dst0)->saturate = true;
EXPECT_PROGRESS(brw_opt_saturate_propagation, bld);
exp.ADD(dst0, src0, src1)->saturate = true;

While nullity of the CheckedPtr object is checked, writing to a raw
pointer safely requires that several other invariants be satisfied, so
it should be marked as unsafe to reflect that.
