When a GPU hang is detected in radv_gpu_hang_occured() we know
which command buffer is faulty but the bound pipelines might
have been updated during the execution.
The pointers to the radv_pipeline objects are emitted just
after the second trace ID, that way it would be easy to dump
the active shaders at the moment of the hang.

When a batch is submitted, INTEL_DEBUG=bat prints a message indicating
which part of the code triggered the flush, and some statistics about
the batch/state buffer utilization.
It also decodes the batchbuffer in debug builds...which is so much
output that it drowns out the utilization messages, if that's all you
care about.
INTEL_DEBUG=submit now just does the utilization messages.
INTEL_DEBUG=bat continues to do both (as the message is a good indicator
that we're starting decode of a new batch).
v2: Rename from "flush" to "submit" (suggested by Chris) because we
might want "flush" for PIPE_CONTROL debugging someday.

With the shaders in the ssao demo, the nir_opt_if wasn't
working properly without this, after this the if gets optimised
so that loop unrolling gets called.
(loop unrolling fails due to instruction count, but at least
it gets to do that.)

Fix the build for Android Nougat.
The dladdr(3) manpage says that <dlfcn.h> is required. On Linux, the
build succeeded without it because build_id.c includes <link.h> which
includes <dlfcn.h>. On Android, we must include <dlfcn.h> directly.

This patch renames build_id_find_nhdr() to
build_id_find_nhdr_for_addr(), and changes it to never examine the
library name.
Tested on Fedora by confirming that build_id_get_data() returns the same
build-id as the file(1) tool. For BSD, I confirmed that the API used
(dladdr() and struct Dl_info) is documented in FreeBSD's manpages.
This solves two problems:
- We can now the query the build-id without knowing the installed library's
filename.
This matters because Android requires specific filenames for HAL
modules, such as "/vendor/lib/hw/vulkan.${board}.so". The HAL
filenames do not follow the Unix convention of "libfoo.so". In
other words, the same query code will now work on Linux and Android.
- Querying the build-id now works correctly when the process
contains multiple shared objects with the same basename.
(Admittedly, this is a highly unlikely scenario).

The GLSL rules for interpolateAtSample are unfortunate:
"Returns the value of the input interpolant variable at
the location of sample number sample. If
multisample buffers are not available, the input
variable will be evaluated at the center of the pixel.
If sample sample does not exist, the position used to
interpolate the input variable is undefined."
This fix will fallback to monolithic shader compilation when
interpolateAtSample is used without multisampling.
One alternative would be to always upload 16 sample positions,
filling the buffer up with repetition when the actual number of
samples is less, and then ANDing the sample ID with 0xf. However,
that punishes all well-behaving users of interpolateAtSample,
when in reality, only conformance tests should be affected by
the issue.
