nv50,nvc0: make resolve sampler objects allow sRGB conversion

Just figured out what that bit does.

Note: It's converted back to sRGB on write, so no effective
conversion occurs.

Revert "gallium: specify resource_resolve destination via a pipe_surface"

This reverts commit 5d5af7d359e0060fa00b90a8f04900b96f9058b0.

It turns out the issue this was supposed to fix merely counter-acted
a bug in the hardware driver that I wasn't aware of.

The resource_resolve is not supposed to do sRGB conversion, period.
(This would violate the requirement that source and destination must
be of the same format).

r200: get rid of dubious aux scissor bits

no point in emitting aux scissor values if we
a) never enable them
b) never set the actual values

plus it is enough to have that aux scissor enable reg (which we never set to
enable) in one place not two.

radeon/r200: get rid of some unneeded cliprect/scissor code

r200: get rid of old gart memory functions from old dri1

radeon/r200: fix bogus clears

There were several problems with these functions (which are a remnant
of dri1 hyperz mostly - should bring it back somehow someday).
First, it would always do a swrast clear if the buffer to clear was a fbo.
Second, for buffers we wouldn't handle the clear (I guess aux/accum?) we
would actually still have tried to clear that later even when we already
cleared it with swrast.

radeon/r200: fix bogus assert/scissor wrt width/height 2048

This addresses one issue raised in bug #51658 discovered by Eugene St Leger.
The assert is bogus since there's no problem with texture width/height being
2048 (the width/height programmed is width/height minus one).
OTOH though the programmed size for scissor rect should be width/height
minus one too otherwise bad things may happen (as it is inclusive, and there's
not enough bits for more than a value of 2047).

SI does not support 64-bit immediates natively, but llvm will generate

pointers).  The i64 indices will always be small enough to fit into

radeon/llvm: Add instruction defs for branches on SI

radeon/llvm: Fix VOPC and V_CNDMASK encoding

radeon/llvm: Assert if we try to copy SCC reg

radeon/llvm: Add SI DAG optimizations for setcc, select_cc

These are needed for correctly lowering branch instructions in some
cases.

radeon/llvm: Add support for encoding SI branch instructions

radeon/llvm: Add special nodes for SALU operations on VCC

The VCC register is tricky because the SALU views it as 64-bit, but the
VALU views it as 1-bit.  In order to deal with this we've added some
special bitcast and binary operations to help convert from the 64-bit
SALU view to the 1-bit VALU view and vice versa.

radeon/llvm: Add i1 registers for SI.

radeon/llvm: Fix CCReg definitions on SI

radeonsi: Enable PIPE_SHADER_CAP_INTEGERS

radeonsi: Add support for loading integers from constant memory

radeon/llvm: Add bitconvert patterns for SI

radeon/llvm: Add custom lowering for SELECT_CC nodes on SI

radeon/llvm: Move conditional pattern leafs to common tablegen file

radeon/llvm: Implement getSetCCResultType for SI

radeon/llvm: Custom lower BR_CC for SI

radeon/llvm: Move lowering of BR_CC node to R600ISelLowering

SI will handle BR_CC different from R600, so we need to move it
out of the shared instruction selector.

radeon/llvm: Move lowering of SETCC node to R600ISelLowering

SI will handle SETCC different from R600, so we need to move it
out of the shared instruction selector.

radeon/llvm: Use correct node type when lowering SETCC
