i965/fs: Match destination type to size for ballot

No use in taking a 64-bit value when we know the high 32-bits are zero.

nir: Reduce destination size of ballot intrinsic when possible

Some hardware, like i965, doesn't support group sizes greater than 32.
In that case, we can reduce the destination size of the ballot
intrinsic, which will simplify our code generation.

i965/fs: Do not move MOVs writing the flag outside of control flow

The implementation of ballotARB() will start by zeroing the flags
register. So, a doing something like

        if (gl_SubGroupInvocationARB % 2u == 0u) {
                ... = ballotARB(true);
[...]
        } else {
                ... = ballotARB(true);
[...]
}

(like fs-ballot-if-else.shader_test does) would generate identical MOVs
to the same destination (the flag register!), and we definitely do not
want to pull that out of the control flow.

Revert "i965: Call intel_prepare_render() from intel_update_state()"

This reverts commit b7153c3e9f9d2d430b0338313587a00e531e4800.

The point of that commit was to ensure intel_prepare_render() occurred
before color resolves on the current framebuffer.  In 0673bbfd9ba16be8
(i965: Move surface resolves back to draw/dispatch time), Jason moved
brw_predraw_resolve_framebuffer back to draw time, which is already
after a intel_prepare_render() call.  So, this is no longer necessary.

Furthermore, it caused problems.  "mpv" would only display a small
corner of movies, and Android started failing camera CTS tests.

This is because intel_prepare_render() ended up handling DRI2 events
which caused the drawable to be resized at an inopportune time, flagging
ctx->NewState |= _NEW_BUFFERS, but at a point where we've already copied
ctx->NewState, and failed to notice the newly set flag.

The lack of _NEW_BUFFERS caused us to skip 3DSTATE_DRAWING_RECTANGLE,
so the drawing ended up being clipped to an outdated framebuffer size.

Just drop the hack and go back to handling this at the proper time.

Thanks to Matti Hämäläinen (ccr), Tomasz Figa (tfiga), and Tapani Palli
for reporting these issues.

util: Make CLAMP turn NaN into MIN.

The previous implementation of CLAMP() allowed NaN to pass through
unscathed, by failing both comparisons.  NaN isn't exactly a value
between MIN and MAX, which can break the assumptions of many callers.

This patch changes CLAMP to convert NaN to MIN, arbitrarily.  Callers
that need NaN to be handled in a specific manner should probably open
code something, or use a macro specifically designed to do that.

Section 2.3.4.1 of the OpenGL 4.5 spec says:

   "Any representable floating-point value is legal as input to a GL
    command that requires floating-point data. The result of providing a
    value that is not a floating-point number to such a command is
    unspecified, but must not lead to GL interruption or termination.
    In IEEE arithmetic, for example, providing a negative zero or a
    denormalized number to a GL command yields predictable results,
    while providing a NaN or an infinity yields unspecified results."

While CLAMP may apply to more than just GL inputs, it seems reasonable
to follow those rules, and allow MIN as an "unspecified result".

This prevents assertion failures in i965 when running the games
"XCOM: Enemy Unknown" and "XCOM: Enemy Within", which call

   glTexEnv(GL_TEXTURE_FILTER_CONTROL_EXT, GL_TEXTURE_LOD_BIAS_EXT,
            -nan(0x7ffff3));

presumably unintentionally.  i965 clamps the LOD bias to be in range,
and asserts that it's in the proper range when converting to fixed
point.  NaN is not, so it crashed.  We'd like to at least avoid that.
