I'm introducing a new machine model to simultaneously allow simple
subtarget CPU descriptions and support new features of
MachineScheduler.
MachineModel has three categories of data:
1) Basic properties for coarse grained instruction cost model.
2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD).
3) Instruction itineraties for detailed per-cycle reservation tables.
These will all live side-by-side. Any subtarget can use any
combination of them. Instruction itineraries will not change in the
near term. In the long run, I expect them to only be relevant for
in-order VLIW machines that have complex contraints and require a
precise scheduling/bundling model. Once itineraries are only actively
used by VLIW-ish targets, they could be replaced by something more
appropriate for those targets.
This tablegen backend rewrite sets things up for introducing
MachineModel type #2: per opcode/operand cost model.

Finish fixing the MachineOperand hashing, providing a nice modern
hash_value overload for MachineOperands. This addresses a FIXME
sufficient for me to remove it, and cleans up the code nicely too.
The important changes to the hashing logic:
- TargetFlags are now included in all of the hashes. These were complete
missed.
- Register operands have their subregisters and whether they are a def
included in the hash.
- We now actually hash all of the operand types. Previously, many
operand types were simply *dropped on the floor*. For example:
- Floating point immediates
- Large integer immediates (>64-bit)
- External globals!
- Register masks
- Metadata operands
- It removes the offset from the block-address hash; I'm a bit
suspicious of this, but isIdenticalTo doesn't consider the offset for
black addresses.
Any patterns involving these entities could have triggered extreme
slowdowns in MachineCSE or PHIElimination. Let me know if there are PRs
you think might be closed now... I'm looking myself, but I may miss
them.

The hash function for MI expressions, used by MachineCSE, is really
broken. This patch fixes the superficial problems which lead to the
intractably slow compile times reported in PR13225.
The specific issue is that we were failing to include the *offset* of
a global variable in the hash code. Oops. This would in turn cause all
MIs which were only distinguishable due to operating on different
offsets of a global variable to produce identical hash functions. In
some of the test cases attached to the PR I saw hash table activity
where there were O(1000) probes-per-lookup *on average*. A very few
entries were responsible for most of these probes.
There is still quite a bit more to do here. The ad-hoc layering of data
in MachineOperands makes them *extremely* brittle to hash correctly.
We're missing quite a few other cases, the only ones I've fixed here are
the specific MO types which were allowed through the assert() in
getOffset().

Allow trailing physreg RegisterSDNode operands on non-variadic instructions.
Also allow trailing register mask operands on non-variadic both
MachineSDNodes and MachineInstrs.
The extra physreg RegisterSDNode operands are added to the MI as
<imp-use> operands. This makes it possible to have non-variadic call
instructions.
Call and return instructions really are non-variadic, the argument
registers should only be used implicitly - they are not part of the
encoding.

Ensure CopyToReg nodes are always glued to the call instruction.
The CopyToReg nodes that set up the argument registers before a call
must be glued to the call instruction. Otherwise, the scheduler may emit
the physreg copies long before the call, causing long live ranges for
the fixed registers.
Besides disabling good register allocation, that can also expose
problems when EmitInstrWithCustomInserter() splits a basic block during
the live range of a physreg.
