nir/search: Don't match inexact expressions with exact subexpressions

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.

i965: Add an INTEL_PRECISE_TRIG=1 option to fix SIN/COS output range.

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.

When enabled, fixes 16 dEQP precision tests

   dEQP-GLES31.functional.shaders.builtin_functions.precision.
   {cos,sin}.{highp,mediump}_compute.{scalar,vec2,vec4,vec4}.

at the cost of making every sin and cos call more expensive (about
twice the number of cycles on recent hardware).  Enabling this
option has been shown to reduce GPUTest Volplosion performance by
about 10%.
