i965/miptree: Check tex image allocation failures

allowing graceful failure instead of crash on assert later on.

This can be hit, for example, on SNB when trying to allocate
8kx8k CUBE_MAP against isl: x-tiled buffer size becomes
2421161984 exceeding the maximum of 1 << 31 == 2147483648.

Another way to hit this on SNB is with multisampling of over
64-bit formats.

gallivm: handle call attributes for llvm < 4.0 in lp_add_function_attr

We had some caller using LLVMAddInstrAttributes, which couldn't be
converted to lp_add_function_attr, because attributes were only handled
for functions in this case, so fix this.
For llvm >= 4.0, this already works correctly.
(radeonsi seems to avoid setting call site attributes prior to llvm 4.0,
the patch then citing it doesn't work when calling intrinsics. But at
least for calling external functions we always used that, albeit only
for actual call attributes, not call parameter attributes, though some
quick test shows llvm seems to handle that as well. The attribute index
is sort of iffy though, since attribute 0 of the call is the actual function,
attribute 1 corresponds to the first parameter of the called function.)
(Verified with GALLIVM_DEBUG=dumpbc plus llvm-dis that the correct
attributes are shown for calls, both for llvm 4.0 and 3.3.)

Revert "i965: Call intel_prepare_render() from intel_update_state()"

This reverts commit b7153c3e9f9d2d430b0338313587a00e531e4800.

The point of that commit was to ensure intel_prepare_render() occurred
before color resolves on the current framebuffer.  In 0673bbfd9ba16be8
(i965: Move surface resolves back to draw/dispatch time), Jason moved
brw_predraw_resolve_framebuffer back to draw time, which is already
after a intel_prepare_render() call.  So, this is no longer necessary.

Furthermore, it caused problems.  "mpv" would only display a small
corner of movies, and Android started failing camera CTS tests.

This is because intel_prepare_render() ended up handling DRI2 events
which caused the drawable to be resized at an inopportune time, flagging
ctx->NewState |= _NEW_BUFFERS, but at a point where we've already copied
ctx->NewState, and failed to notice the newly set flag.

The lack of _NEW_BUFFERS caused us to skip 3DSTATE_DRAWING_RECTANGLE,
so the drawing ended up being clipped to an outdated framebuffer size.

Just drop the hack and go back to handling this at the proper time.

Thanks to Matti Hämäläinen (ccr), Tomasz Figa (tfiga), and Tapani Palli
for reporting these issues.

i965/miptree: Switch to isl_surf::samples

v2 (Jason):
   - Don't trigger miptree re-creation in vain later on with ISL
     based. Core GL uses zero to indicate single sampled while
     ISL uses one - this would cause intel_miptree_match_image()
     to always fail.
   - Now that native miptree is already using sample number of
     one, there is no need for MAX2() when converting to ISL.

i965/miptree: Use num_samples of 1 instead of 0 for single-sampled

Patch moves "assert(brw->num_samples <= 16)" from
emit_3dstate_multisample2() to upload_multisample_state(). Latter
is the only caller of the former and passes "brw->num_samples"
as argument. Therefore it is clearer to assert in the caller.

Possible bug fix in genX(emit_3dstate_multisample2) which
doesn't have a case for num_samples == 0 in the switch
statement.

It should be noted that intel_miptree_map()/unmap() now checks
additionally for "mt->surf.samples == 1" in order to support gen6
stencil which is already transitioned to ISL. This will go away in
next patch when native miptrees start to use isl_surf::samples as
well.
