i965: Grow the batch/state buffers if we need space and can't flush.

Previously, we would just assert fail and die in this case.  The only
safeguard is the "estimated max prim size" checks when starting a draw
(or compute dispatch or BLORP operation)...which are woefully broken.

Growing is fairly straightforward:

1. Allocate a new larger BO.
2. memcpy the existing contents over to the new buffer
3. Set the new BO to the same GTT offset as the old BO.  When emitting
   relocations, we write the presumed GTT offset of the target BO.  If
   we changed it, we'd have to update all the existing values (by
   walking the relocation list and looking at offsets), which is more
   expensive.  With the old BO freed, ideally the kernel could simply
   place the new BO at that offset anyway.
4. Update the validation list to contain the new BO.
5. Update the relocation list to have the GEM handle for the new BO

i965: Use a separate state buffer, but avoid changing flushing behavior.

Previously, we emitted GPU commands and indirect state into the same
buffer, using a stack/heap like system where we filled in commands from
the start of the buffer, and state from the end of the buffer.  We then
flushed before the two met in the middle.

Meeting in the middle is fatal, so you have to be certain that you
reserve the correct amount of space before emitting commands or state
for a draw.  Currently, we will assert !no_batch_wrap and die if the
estimate is ever too small.  This has been mercifully obscure, but has
happened on a number of occasions, and could in theory happen to any
application that issues a large draw at just the wrong time.

Estimating the amount of batch space required is painful - it's hard to
get right, and getting it right involves a lot of code that would burn
CPU time, and also be painful to maintain.  Rolling back to a saved
state and retrying is also painful - failing to save/restore all the
required state will break things, and redoing state emission burns a
lot of CPU.  memcpy'ing to a new batch and continuing is painful,
because commands we issue for a draw depend on earlier commands as well
(such as STATE_BASE_ADDRESS, or the GPU being in a pirtacular state).

The best plan is to never run out of space, which is totally doable but
pretty wasteful - a pessimal draw requires a huge amount of space, and
rarely occurs.  Instead, we'd like to grow the batch buffer if we need
more space and can't safely flush.

We can't grow with a meet in the middle approach - we'd have to move the
state to the end, which would mean updating every offset from dynamic
state base address.  Using separate batch and state buffers, where both
fill starting at the beginning, makes it easy to grow either as needed.

This patch separates the two concepts.  We create a separate state
buffer, with a second relocation list, and use that for brw_state_batch.

However, this patch tries to retain the original flushing behavior - it
adds the amount of batch and state space together, as if they were still
co-existing in a single buffer.  The hope is to flush at the same time
as before.  This is necessary to avoid provoking bugs caused by broken
batch wrap handling (which we'll fix shortly).  It also avoids suddenly
increasing the size of the batch (due to state not taking up space),
which could have a significant performance impact.  We'll tune it later.

v2:
- Mark the statebuffer with EXEC_OBJECT_CAPTURE when supported (caught
  by Chris).  Unfortunately, we lose the ability to capture state data
  on older kernels.
- Continue to support the malloc'd shadow buffers.

glsl: avoid accessing invalid memory after get_variable_being_redeclared()

After get_variable_being_redeclared() has been called, it is no longer
safe to access the original variable pointer, since its memory might have
been freed.

Since callers of this function should only be accessing the variable pointer
returned by the function, avoid potential bugs by re-assigning the
original variable pointer to the result of the function call,
making it impossible for the remaining code to access an invalid variable
pointer.

glsl: make the redeclared variable NULL if it is deleted

get_variable_being_redeclared() can delete the original variable
in a specific scenario. The code sets it to NULL after this so other
code in that same function doesn't try to access trashed memory after
the fact, however, the copy of that variable in the caller code
won't see any of this making it very easy to overlook.

Make the function a bit safer by taking a pointer to the original
variable so we can also make NULL the caller's pointer to the variable
if this function deletes it.

i965: Add an INTEL_DEBUG=submit option for printing batch statistics.

the batch/state buffer utilization.

It also decodes the batchbuffer in debug builds...which is so much

util: Query build-id by symbol address, not library name

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).

radeonsi: hard-code pixel center for interpolateAtSample without multisample buffers

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.
