Christian Konig 2aca043312 R600/SI: replace SI_V_CNDLT with a pattern
It actually fixes quite a bunch of piglit tests.

This is a candidate for the mesa-stable branch.

Christian Konig a881179ffe R600/SI: nuke SReg_1 v3
It's completely unnecessary and can be replace with proper
SReg_64 handling instead.

This actually fixes a piglit test on SI.

v2: use correct register class in addRegisterClass,
    set special classes as not allocatable
v3: revert setting special classes as not allocateable

This is a candidate for the stable branch.

Michel Danzer e9bb18b555 R600/SI: Fix int_SI_fs_interp_constant
The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.

In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.

NOTE: This is a candidate for the Mesa stable branch.

Tom Stellard c4cabef782 R600: Proper insert S_WAITCNT instructions
Some instructions like memory reads/writes are executed
asynchronously, so we need to insert S_WAITCNT instructions
to block before accessing their results. Previously we have
just inserted S_WAITCNT instructions after each async
instruction, this patch fixes this and adds a prober
insertion pass.

Tom Stellard f8794354b2 R600: New control flow for SI v2
This patch replaces the control flow handling with a new
pass which structurize the graph before transforming it to
machine instruction. This has a couple of different advantages
and currently fixes 20 piglit tests without a single regression.

It is now a general purpose transformation that could be not
only be used for SI/R6xx, but also for other hardware
implementations that use a form of structurized control flow.

v2: further cleanup, fixes and documentation
