Simon Pilgrim b69dae42e3 [X86][AVX512] Tag GATHER/SCATTER instruction scheduler classes
NOTE: At the moment these use the WriteLoad/WriteStore classes, which severely underestimates the costs. This needs to be reviewed.

Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

Craig Topper e5d44cefea [X86] Teach EVEX->VEX pass to turn SHUFI32X4/SHUFF32X4/SHUFI64X/SHUFF64X2 into VPERM2F128/VPERM2I128.
This recovers some of the tests that were changed by r317403.

Craig Topper a96d62b360 [X86] Teach shuffle lowering to use 256-bit SHUF128 when possible.
This allows masked operations to be used and allows the register allocator to use YMM16-31 if necessary.

As a follow up I'll look into teaching EVEX->VEX how to turn this back into PERM2X128 if any of the additional features don't work out.

Gadi Haber 323f2e1715 [X86][Broadwell] Added the instruction scheduling information for the Broadwell CPU.
Adding the scheduling information for the Browadwell (BDW) CPU target.

This patch adds the instruction scheduling information for the Broadwell (BDW) architecture target by adding the file X86SchedBroadwell.td located under the X86 Target.
We used the scheduling information retrieved from the Broadwell architects in order to create the file.
The scheduling information includes latency, number of micro-Ops and used ports by each BDW instruction.

The patch continues the scheduling replacement and insertion effort started with the SandyBridge (SNB) target in r310792, the Haswell (HSW) target in r311879, the SkylakeClient (SKL) target in rL313613 + rL315978 and the SkylakeServer (SKX) in rL315175.

Performance fluctuations may be expected due to code alignment effects.

Gadi Haber 1e0f1f476a [X86][SKL] Updated scheduling information for the SkylakeClient target
Updated the scheduling information for the SkylakeClient target with the following changes:

1. regrouped the instructions after adding load and store latencies.
2. regrouped the instructions after adding identified missing ports in several groups.
The changes were made after revisiting the latencies impact of all the load and store uOps.

Gadi Haber 684944b822 [X86][SKX] Adding the scheduling information for the SKX target.
Adding the scheduling information for the SkylakeServer (SKX) target.

This patch adds the instruction scheduling information for the SkylakeServer (SKX) architecture target by adding the file X86SchedSkylakeServer.td located under the X86 Target.
We used the scheduling information retrieved from the Skylake architects in order to create the file.
The scheduling information includes latency, number of micro-Ops and used ports by each SKL instruction.

The patch continues the scheduling replacement and insertion effort started with the SNB target in r310792, the HSW target in r311879 and the SkylakeClient (SKL) target in rL313613.

Ashutosh Nema bfcac0b480 AMD family 17h (znver1) scheduler model update.
Summary:
This patch enables the following:
1) Regex based Instruction itineraries for integer instructions.
2) The instructions are grouped as per the nature of the instructions
   (move, arithmetic, logic, Misc, Control Transfer). 
3) FP instructions and their itineraries are added which includes values
   for SSE4A, BMI, BMI2 and SHA instructions.

Craig Topper 106b5b6856 AMD znver1 Initial Scheduler model
Summary:
This patch adds the following
1. Adds a skeleton scheduler model for AMD Znver1.
2. Introduces the znver1 execution units and pipes.
3. Caters the instructions based on the generic scheduler classes.
4. Further additions to the scheduler model with instruction itineraries will be carried out incrementally based on
        a. Instructions types
        b. Registers used
5. Since itineraries are not added based on instructions, throughput information are bound to change when incremental changes are added.
6. Scheduler testcases are modified accordingly to suit the new model.

Patch by Ganesh Gopalasubramanian. With minor formatting tweaks from me.
