R600: initial scheduler code
This is a skeleton for a pre-RA MachineInstr scheduler strategy. Currently
it only tries to expose more parallelism for ALU instructions (this also
makes the distribution of GPR channels more uniform and increases the
chances of ALU instructions to be packed together in a single VLIW group).
Also it tries to reduce clause switching by grouping instruction of the
same kind (ALU/FETCH/CF) together.
Vincent Lejeune:
- Support for VLIW4 Slot assignement
- Recomputation of ScheduleDAG to get more parallelism opportunities
Tom Stellard:
- Fix assertion failure when trying to determine an instruction's slot
based on its destination register's class
- Fix some compiler warnings
Vincent Lejeune: [v2]
- Remove recomputation of ScheduleDAG (will be provided in a later patch)
- Improve estimation of an ALU clause size so that heuristic does not emit cf
instructions at the wrong position.
- Make schedule heuristic smarter using SUnit Depth
- Take constant read limitations into account
Vincent Lejeune: [v3]
- Fix some uninitialized values in ConstPair
- Add asserts to ensure an ALU slot is always populated

R600: Remove LowerConstCopyPass and lower CONST_COPY right after ISel.
Maintaining CONST_COPY Instructions until Pre Emit may prevent some ifcvt case

R600/SI: cleanup literal handling v3
Seems to be allot simpler, and also paves the
way for further improvements.
v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
use VGPR0 in dummy EXP, avoid compiler warning, break
after encoding the first literal.
v3: correctly use V_ADD_F32_e64
This is a candidate for the stable branch.

R600: Support for indirect addressing v4
Only implemented for R600 so far. SI is missing implementations of a
few callbacks used by the Indirect Addressing pass and needs code to
handle frame indices.
At the moment R600 only supports array sizes of 16 dwords or less.
Register packing of vector types is currently disabled, which means that a
vec4 is stored in T0_X, T1_X, T2_X, T3_X, rather than T0_XYZW. In order
to correctly pack registers in all cases, we will need to implement an
analysis pass for R600 that determines the correct vector width for each
array.
v2:
- Add support for i8 zext load from stack.
- Coding style fixes
v3:
- Don't reserve registers for indirect addressing when it isn't
being used.
- Fix bug caused by LLVM limiting the number of SubRegIndex
declarations.
v4:
- Fix 64-bit defines

R600: rework handling of the constants
Remove Cxxx registers, add new special register - "ALU_CONST" and new
operand for each alu src - "sel". ALU_CONST is used to designate that the
new operand contains the value to override src.sel, src.kc_bank, src.chan
for constants in the driver.

Vincent Lejeune:
- Use pointers for constants
- Fold CONST_ADDRESS when possible
Tom Stellard:
- Give CONSTANT_BUFFER_0 its own address space
- Use integer types for constant loads

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.

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
