RADV_PERFTEST=outooforder has been removed a while ago. This fixes

This can be usefull for debugging the on disk cache, but is also
useful in the following patch for secure compiles which will be
used to compile huge pipeline collections. These pipeline
collections can be multiple GBs and the in memory cache grows to
multiple GBs very quickly when they are compiled so we want to
be able to turn off the in memory cache.

This new option can help debug shader compiler problems when

This debug option allows vkGet[Instance/Device]ProcAddr() to succeed
even if the extension associated with the requested entrypoint was not
enabled.
This has come in handy in a few instances when debugging VR
applications, so I thought it would be good to have a cleaned up version
upstreamed.

Quite useless without DCC for LAYOUT_GENERAL.
Fixes: b4dad3afaa Revert "radv: Do not decompress on LAYOUT_GENERAL."
Acked-by: Dave Airlie <airlied@redhat.com>
This allows us to disable the FMASK decompress pass when
transitioning from CB writes to shader reads.
This will likely be improved and enabled by default in the future.
No CTS regressions on GFX8 but a few number of multisample CTS
failures on GFX9 (they look related to the small hint).

The load/store optimizer pass doesn't handle WaW hazards correctly
and this is the root cause of the reflection issue with Monster
Hunter World. AFAIK, it's the only game that are affected by this
issue.
This is fixed with LLVM r361008, but we need a workaround for older
LLVM versions unfortunately.

After doing a bunch of benchmarks, primitive binning helps
some games like The Talos Principle (+5%) or Serious Sam 2017
(+3%). For other titles, either it doesn't change anything or
it hurts very few (less than 1%).
This only affects GFX9.

This uses the common compiler passes abstraction to help radv
avoid fixed cost compiler overheads. This uses a linked list per
thread stored in thread local storage, with an entry in the list
for each target machine.
This should remove all the fixed overheads setup costs of creating
the pass manager each time.
This takes a demo app time to compile the radv meta shaders on nocache
and exit from 1.7s to 1s. It also has been reported to take the startup
time of uncached shaders on RoTR from 12m24s to 11m35s (Alex)
v2: fix llvm6 build, inline emit function, handle multiple targets
in one thread
v3: rebase and port onto new structure
v4: rename some vars (Bas)
v5: drag all code into radv for now, we can refactor it out later
for radeonsi if we make it shareable
v6: use a bit more C++ in the wrapper
v7: logic bugs fixed so it actually runs again.
v8: rebase on top of radeonsi changes.
v9: drop some C++ headers, cleanup list entry
v10: use pop_back (didn't have enough caffeine)

This adds a RADV_DEBUG=startup option to dump more info about
instance creation and device enumeration.
A common question end users have is why the direver is not loading
for them, and this has two common reasons:
1) They did not install the driver.
2) AMDGPU is not used for the card in the kernel.
This adds some info messages so we can easily get a some useful
output from end users.

Errors are not that common of a case so we can eat a slight perf
hit in having to call a function and do a runtime check.
In turn this makes debugging random errors happening for end users
easier, because they don't have to have a debug build on hand.

As the implementation is conservative, we can now enable it

Don't expect much more than 1% of improvements, but the gain
seems consistent.

This can be enabled with RADV_PERFTEST=dccmsaa.
DCC for MSAA textures is actually not as easy to implement. It
looks like there is some corner cases. I will improve support
incrementally.
Vega support, as well as Polaris improvements, will be added later.

Disabled by default for now, it can be enabled with

No CTS regressions on Polaris, and all Vulkan games I tested

Expect small performance improvements for applications where
out-of-order rasterization can be enabled by the driver.
Loosely based on RadeonSI.
