Our existing functions, brw_math and brw_math2, had unclear roles:

Gen4-5 used brw_math for both unary and binary math functions; it never
used brw_math2.  Since operands are already in message registers, this
is reasonable.

Gen6+ used brw_math for unary math functions, and brw_math2 for binary
math functions, duplicating a lot of code.  The only real difference was
that brw_math used brw_null_reg() for src1.

This patch improves brw_math2's assertions to allow both unary and

If need is positive or 0:

        0 goes to 1024, 512 goes to 1024 as well, 1025 goes
        to 2048 and so on. So now need is always possitive,
        we do compute_memory_grow_pool, check its output
        and continue.

If need is negative:
    we calculate need += 1024 - (need % 1024), in this case
        we will have negative numbers, and if need is
        [-1024:-1] 0, so now we take the else, recalculate
        need as need = pool->size_in_dw / 10 and
        need += 1024 - (need % 1024), we do
        compute_memory_grow_pool, check its output and continue.

AFTER:
If need is positive or 0:
    we jump the if, calculate need += 1024 - (need % 1024)
        compute_memory_grow_pool, check its output and continue.

If need is negative:
    we enter the if, and need is now pool->size_in_dw / 10.
        Now we calculate need += 1024 - (need % 1024)

i965: Ensure that we end instruction streams properly.

Threads must terminate with a SEND message to a particular shared function,
such as a URB write or FB write, so the instruction stream really shouldn't
ever end in an IF/ELSE/ENDIF or similar block structure.

However, if the instruction stream (incorrectly) ends in a block structure
the last block's end pointer will not be set, leading to a crash later on in
fs_live_variables::setup_def_use(). It is better to detect this earlier, so
assert on that.

i965/fs: Add Gen < 6 runtime checks for line antialiasing.

In Gen < 6 the hardware generates a runtime bit that indicates whether AA data
has to be sent as part of the framebuffer write SEND message. This affects the
specific case where we have setup antialiased line rendering and we render
polygons which have one face setup in GL_LINE mode (line antialiasing
will be used) and the other one in GL_FILL mode (no line antialiasing needed).

Currently we are not doing this runtime test and instead we always send AA
data, which produces incorrect rendering of the GL_FILL face of the polygon in
in the aforementioned scenario (verified in ironlake and gm45).

In Gen4 this is, likely, a regression introduced with commit 098acf6c843. In
Gen5 this has never worked properly. Gen > 5 are not affected by this.

The patch fixes the problem by adding the appropriate runtime check and
adjusting the framebuffer write message accordingly in the conflictive
scenario.
