Been on my TODO list for a while. If nothing else this will make gdb
properly grok the opc_t enum.
This first step preserves ir3_instruction::category (with an added
assert that category matches what is encoded in opc_t). Next step is
to drop the category field (and arg to ir3_instr_create()), but that
is split into next commit for bisectability and so that we can run
piglit in the intermediate state to flush out any problems.

Our hardware requires an LOD for all texelFetch commands even if they are
on buffer textures. GLSL IR gives us an LOD of 0 in that case, but the LOD
is really rather meaningless. This commit allows other NIR producers to be
more lazy and not provide one at all.

lower_variable_index_to_cond_assign() did not handle system values.
gl_SampleMaskIn[] is a system value, and also an array. Accessing it
with a variable index would trigger an unreachable() assert.
Rather than adding a new EmitNoIndirectSystemValues flag, we simply
lower unconditionally. There is exactly one case where this occurs,
and for all current drivers, lowering produces optimal code. Even
for future drivers with 32x MSAA, it produces reasonable code.

In the first pass of implementing exact handling, I made a mistake with
search-and-replace. In particular, we only reallly handled exact/inexact
on the root of the tree. Instead, we need to check every node in the tree
for an exact/inexact match. As an example of this, consider the following
GLSL code
precise float a = b + c;
if (a < 0) {
do_stuff();
}
In that case, only the add will be declared "exact" and an expression that
looks for "b + c < 0" will still match and replace it with "b < -c" which
may yield different results. The solution is to simply bail if any of the
values are exact when matching an inexact expression.

The SIN and COS instructions on Intel hardware can produce values
slightly outside of the [-1.0, 1.0] range for a small set of values.
Obviously, this can break everyone's expectations about trig functions.
According to an internal presentation, the COS instruction can produce
a value up to 1.000027 for inputs in the range (0.08296, 0.09888). One
suggested workaround is to multiply by 0.99997, scaling down the
amplitude slightly. Apparently this also minimizes the error function,
reducing the maximum error from 0.00006 to about 0.00003.
