The i965 MUL instruction doesn't natively support 32-bit by 32-bit
integer multiplication; additional instructions (MACH/MOV) are required.
However, we can avoid those if we know one of the operands can be
represented in 16 bits or less. The vector backend's is_16bit_constant
static helper function checks for this.
We want to be able to use it in the scalar backend as well, which means
moving the function to a more generally-usable location. Since it isn't
i965 specific, I decided to make it an ir_constant method, in case it
ends up being useful to other people as well.
v2: Rename from is_16bit_integer_constant to is_uint16_constant, as
suggested by Ilia Mirkin. Update comments to clarify that it does
apply to both int and uint types, as long as the value is
non-negative and fits in 16-bits.

These are clearly needed---the comments in the function are even present
for each one of them. I originally had two separate state atoms for
3DSTATE_SBE and 3DSTATE_SBE_SWIZ. When I combined the functions, I must
have forgotten to add the atoms for 3DSTATE_SBE_SWIZ.

Binding a new destination may cause the svga driver to emit draw calls
while propagating the surface. Make sure this doesn't happen in the middle
of sampler state setup where state may be incosistent.
In practice, surface propagation should never happen here and even if it did,
it wouldn't be a valid reason for the svga driver to emit partially set up
state, but to avoid future uncertainties, make sure this doesn't happen
anyway.
Found while auditing the state tracker for inconsistent sampler state /
sampler view setup.

It's more likely that we won't find writes to all channels than one will
interfere, and calculating interference is more expensive. This change
will also help prepare for coalescing load_payload instructions'
operands.
Also update the live intervals for all channels, and not just the last
that we saw.
