i965/fs: Update discard jump to preserve uniform loads via sampler.

Commit 17c7ead7 exposed a bug in how uniform loading happens in the
presence of discard.  It manifested itself in an application as
randomly incorrect pixels on the borders of conditional areas.

This is due to how discards jump to the end of the shader incorrectly
for some channels.  The current implementation checks each 2x2
subspan to preserve derivatives.  When uniform loading via samplers
was turned on, it uses a full execution mask, as stated in
lower_uniform_pull_constant_loads(), and only populates four channels
of the destination (see generate_uniform_pull_constant_load_gen7()).
It happens incorrectly when the first subspan has been jumped over.

The series that implemented this optimization was done before the
changes to use samplers for uniform loads.  Uniform sampler loads
use special execution masks and only populate four channels, so we
can't jump over those or corruption ensues.

This fix only jumps to the end of the shader if all relevant channels
are disabled, i.e. all 8 or 16, depending on dispatch.  This
preserves the original GLbenchmark 2.7 speedup noted in commit
beafced2.

It changes the shader assembly accordingly:

before   : (-f0.1.any4h)  halt(8)  17 2  null { align1 WE_all 1Q };
after(8) : (-f0.1.any8h)  halt(8)  17 2  null { align1 WE_all 1Q };
after(16): (-f0.1.any16h) halt(16) 17 2  null { align1 WE_all 1H };

i965/vec4: Remove useless conditionals.

Setting a couple of bits is the same cost or less as conditionally

i965/fs: Pass cfg to calculate_live_intervals().

We've often created the CFG immediately before, so use it when
available.

i965: Mark fields in the live interval classes protected.

cfg, for instance, is a pointer to a local variable in
calculate_live_intervals, certainly not valid after that function has
returned.

Reviewed-by: Roland Scheidegger <sroland@vmware.com>

st/mesa: fix incorrect size of UBO declarations

UniformBufferSize is in bytes so we need to divide by 16 to get the
number of constant buffer slots.  Also, the ureg_DECL_constant2D()
function takes first..last parameters so we need to subtract one
for the last value.

st/mesa: don't use address register for constant-indexed ir_binop_ubo_load

Before, we were always using the address register and indirect addressing
to index into a UBO constant buffer.  With this change we only do that
when necessary.

Using the piglit bin/arb_uniform_buffer_object-rendering test as an
example:

Shader code:
  uniform ub_rot {float rotation; };
  ...
  m[1][1] = cos(rotation);

Before:
  IMM[1] INT32 {0, 1, 0, 0}
  1: UARL ADDR[0].x, IMM[1].xxxx
  2: MOV TEMP[0].x, CONST[3][ADDR[0].x].xxxx
  3: COS TEMP[1].x, TEMP[0].xxxx

After:
  0: COS TEMP[0].x, CONST[3][0].xxxx
