I initially implemented frexp() as an IR opcode with a lowering pass,

assumptions our optimization passes make about ir_expressions being pure
(i.e., having no side effects).

For example, if opt_tree_grafting encounters this code:

uniform float u;
void main()
{
  int exp;
  float f = frexp(u, out exp);
  float g = float(exp)/256.0;
  float h = float(exp) + 1.0;
  gl_FragColor = vec4(f, g, h, g + h);

it may try to optimize it to this:

uniform float u;
void main()
{

  float h = float(exp) + 1.0;
  gl_FragColor = vec4(frexp(u, out exp), g, h, g + h);
}

Some hardware has an instruction which performs frexp(), but we would
need some other compiler infrastructure to be able to generate it, such
as an intrinsics system that would allow backends to emit specific code
for particular bits of IR.

expects them); if it was inactive, we assigned them in the order of
the gl_varying_slot enum.

This made for unnecessary recompiles, since turning clipping on/off
for a shader that used gl_ClipDistance might rearrange the varyings.
It also required extra bookkeeping, since it required the user
clipping flag to be provided to brw_compute_vue_map() as a parameter.

With this patch, we always put clip distances at in slots 2 and 3 if

for ensuring that clip distances are written to when user clipping is

mesa: Rename MESA_shader_integer_mix to EXT_shader_integer_mix

Everyone at the Khronos meeting was as surprised that GLSL didn't
already support this as we were.  Several vendors said they'd ship it,
but there didn't seem to be enough interest to put in the effort to make
it ARB or KHR.

v2: Fix a couple typos and rename the spec file to
EXT_shader_integer_mix.spec.  Suggested by Roland.
