Here is the final patch to enable dynamic eu instruction store size:
increase the brw eu instruction store size dynamically instead of just
allocating it statically with a constant limit. This would fix something
that 'GL_MAX_PROGRAM_INSTRUCTIONS_ARB was 16384 while the driver would
limit it to 10000'.
v2: comments from ken, do not hardcode the eu limit to (1024 * 1024)

A single next_insn may change the base address of instruction store
memory(p->store), so call it first before referencing the instruction
store pointer from an index.

If dynamic instruction store size is enabled, while after the brw_JMPI()
and before the brw_land_fwd_jump() function, the eu instruction store
base address(p->store) may change. Thus, the safe way to reference the
jmp instruction is by index instead of by the instruction address.

If dynamic instruction store size is enabled, while after
the brw_IF/ELSE() and before the brw_ENDIF() function, the
eu instruction store base address(p->store) may change.
Thus let if_stack just store the instruction index. This is
somehow more flexible and safe than store the instruction
memory address.

This partially reverts commit 363ff84475.
It caused severe performance drops in Nexuiz. Reported by Phoronix.
Tested by me on r300g and by IRC people on r600g.
When updating SOL indices, we were accidentally putting the starting
index in dword 1 and the SVBI number to increment in dword 2--these
should be reversed. Usually both of these values are zero, so we
didn't see any problem. However, if a transform feedback operation
spans multiple batch buffers, the starting index will be nonzero.
Fixes piglit test "EXT_transform_feedback/intervening-read output".

When rendering triangle strips, vertices come down the pipeline in the
order specified, even though this causes alternate triangles to have
reversed winding order. For example, if the vertices are ABCDE, then
the GS is invoked on triangles ABC, BCD, and CDE, even though this
means that triangle BCD is in the reverse of the normal winding order.
The hardware automatically flags the triangles with reversed winding
order as _3DPRIM_TRISTRIP_REVERSE, so that face culling and two-sided
coloring can be adjusted to account for the reversed order.
In order to ensure that winding order is correct when streaming
vertices out to a transform feedback buffer, we need to alter the
ordering of BCD to BDC when the first provoking vertex convention is
in use, and to CBD when the last provoking vertex convention is in
use.
To do this, we precompute an array of indices indicating where each
vertex will be placed in the transform feedback buffer; normally this
is SVBI[0] + (0, 1, 2), indicating that vertex order should be
preserved. When the primitive type is _3DPRIM_TRISTRIP_REVERSE, we
change this order to either SVBI[0] + (0, 2, 1) or SVBI[0] + (1, 0,
2), depending on the provoking vertex convention.
Fixes piglit tests "EXT_transform_feedback/tessellation
triangle_strip" on Gen6.
