[CodeGen][ARM] Enable Swing Module Scheduling for ARM
This patch permits Swing Modulo Scheduling for ARM targets
turns it on by default for the Cortex-M7. The t2Bcc
instruction is recognized as a loop-ending branch.
MachinePipeliner is extended by adding support for
"unpipelineable" instructions. These instructions are
those which contribute to the loop exit test; in the SMS
papers they are removed before creating the dependence graph
and then inserted into the final schedule of the kernel and
prologues. Support for these instructions was not previously
necessary because current targets supporting SMS have only
supported it for hardware loop branches, which have no
loop-exit-contributing instructions in the loop body.
The current structure of the MachinePipeliner makes it difficult
to remove/exclude these instructions from the dependence graph.
Therefore, this patch leaves them in the graph, but adds a
"normalization" method which moves them in the schedule to
stage 0, which causes them to appear properly in kernel and
prologues.
It was also necessary to be more careful about boundary nodes
when iterating across successors in the dependence graph because
the loop exit branch is now a non-artificial successor to
instructions in the graph. In additional, schedules with physical
use/def pairs in the same cycle should be treated as creating an
invalid schedule because the scheduling logic doesn't respect
physical register dependence once scheduled to the same cycle.

We currently emit an error during verification if a pdl.operation with non-inferrable

all dialects have been loaded, which is true at run time, but may not be true when
the PDL is generated (such as via PDLL). This commit fixes this by not emitting the
error if the operation isn't registered, i.e. it uses the `mightHave` variant of trait/interface
methods.
Secondly, we currently don't verify when a pdl.operation has no explicit results, but the
operation being created is known to expect at least one. This commit adds a heuristic
error to detect these cases when possible and fail. We can't always capture when the user
made an error, but we can capture the most common case where the user expected an
operation to infer its result types (when it actually isn't possible).

Unfortunately the implementation has two problems:
1) It didn't actually check for the result number and reject
it. parseRegionArgument and parseOperand were identical.
2) It had a lot of machinery built up around it that paralleled
operand parsing. This also was functionally identical, but
also had some subtle differences (e.g. the parseOptional
stuff had a different result type).
I thought about just removing all of this, but decided that the

This change makes join consistent with equivalence, which also performs
structural comparison. It also fixes a bug where the values are `ReferenceValue`
but the merge creates a non-reference value. This case arises when the
`ReferenceValue`s were created to represent an lvalue, so the "reference-ness"

FixAnyAddress is to be used when we don't know or don't care

By using FixAnyAddress over the others, you document that no

On all existing platforms apart from Arm Thumb, you could use
either FixCodeAddress or FixDataAddress and be fine. Up until
now I've chosen to use FixDataAddress but if I had
chosen to use FixCodeAddress that would have broken Arm Thumb.
Hence FixAnyAddress, to give you the "safest" option when you're

[Flang] Initial lowering of the Fortran Do loop
This patch adds code to lower simple Fortran Do loops with loop control.
Lowering is performed by the the `genFIR` function when called with a
`Fortran::parser::DoConstruct`. `genFIR` function calls `genFIRIncrementLoopBegin`
then calls functions to lower the body of the loop and finally calls
the function `genFIRIncrementLoopEnd`. `genFIRIncrementLoopBegin` is
responsible for creating the FIR `do_loop` as well as storing the value of
the loop index to the loop variable. `genFIRIncrementLoopEnd` returns
the incremented value of the loop index and also stores the index value
outside the loop. This is important since the loop variable can be used
outside the loop. Information about a loop is collected in a structure
`IncrementLoopInfo`.
Note 1: Future patches will bring in lowering for unstructured,
infinite, while loops
Note 2: This patch is part of upstreaming code from the fir-dev branch of
https://github.com/flang-compiler/f18-llvm-project.
