Add a function VLIWPacketizerList::shouldAddToPacket, which will allow
specific implementations to decide if it is profitable to add given
instruction to the current packet.

This will make the depedence graph more accurate if an alias analysis
is provided. If nullptr is specified in its place, the behavior will
remain as it is currently.

Duplicate a few common definitions between DFAPacketizer.cpp and
DFAPacketizerEmitter.cpp to avoid including files from CodeGen
in TableGen.

Extended DFA tablegen to:
- added "-debug-only dfa-emitter" support to llvm-tblgen
- defined CVI_PIPE* resources for the V60 vector coprocessor
- allow specification of multiple required resources
- supports ANDs of ORs
- e.g. [SLOT2, SLOT3], [CVI_MPY0, CVI_MPY1] means:
(SLOT2 OR SLOT3) AND (CVI_MPY0 OR CVI_MPY1)
- added support for combo resources
- allows specifying ORs of ANDs
- e.g. [CVI_XLSHF, CVI_MPY01] means:
(CVI_XLANE AND CVI_SHIFT) OR (CVI_MPY0 AND CVI_MPY1)
- increased DFA input size from 32-bit to 64-bit
- allows for a maximum of 4 AND'ed terms of 16 resources
- supported expressions now include:
expression => term [AND term] [AND term] [AND term]
term => resource [OR resource]*
resource => one_resource | combo_resource
combo_resource => (one_resource [AND one_resource]*)

kparzysz: Verified AMDGPU codegen to be unchanged on all llc
tests, except those dealing with instruction encodings.
Reapply the previous patch, this time without circular dependencies.

ScheduleDAGInstrs doesn't behave differently before or after register
allocation. It was only used in a method of MachineSchedulerBase which
behaved differently in MachineScheduler/PostMachineScheduler. Change
this to let MachineScheduler/PostMachineScheduler just pass in a
parameter to that function.
The order of the LiveIntervals* and bool RemoveKillFlags paramters have
been switched to make out-of-tree code fail instead of unintentionally
passing a value intended for the IsPostRA flag to the (previously
following and default initialized) RemoveKillFlags.

Both MachineLoopInfo and MachineDominatorTree may be null in ScheduleDAGMI
constructor call. It is undefined behavior to take references to these values.
This bug is reported by UBSan.

This fixes a pathological compile time problem with very large blocks
and lots of scheduling boundaries.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Original commit message:
Allow up to 64 functional units per processor itinerary.
This patch changes the type used to hold the FU bitset from unsigned to uint64_t.
This will be needed for some upcoming PowerPC itineraries.
