Krzysztof Parzyszek 709e4f9b73 [Hexagon] Use isMetaInstruction instead of isDebugValue

Chandler Carruth 6bda14b313 Sort the remaining #include lines in include/... and lib/....
I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.

I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.

This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.

Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

Krzysztof Parzyszek a540997ce4 [Hexagon] Separate Hexagon subreg indices for different register classes
For pairs of 32-bit registers: isub_lo, isub_hi.
For pairs of vector registers: vsub_lo, vsub_hi.

Add generic subreg indices: ps_sub_lo, ps_sub_hi, and a function
  HexagonRegisterInfo::getHexagonSubRegIndex(RegClass, GenericSubreg)
that returns the appropriate subreg index for RegClass.

Matthias Braun 1eb473680a MachineFunctionProperties/MIRParser: Rename AllVRegsAllocated->NoVRegs, compute it
Rename AllVRegsAllocated to NoVRegs. This avoids the connotation of
running after register and simply describes that no vregs are used in
a machine function. With that we can simply compute the property and do
not need to dump/parse it in .mir files.

Duncan P. N. Exon Smith f197b1f78f ADT: Remove all ilist_iterator => pointer casts, NFC
Remove all ilist_iterator to pointer casts.  There were two reasons for
casts:

  - Checking for an uninitialized (i.e., null) iterator.  I added
    MachineInstrBundleIterator::isValid() to check for that case.

  - Comparing an iterator against the underlying pointer value while
    avoiding converting the pointer value to an iterator.  This is
    occasionally necessary in MachineInstrBundleIterator, since there is
    an assertion in the constructors that the underlying MachineInstr is
    not bundled (but we don't care about that if we're just checking for
    pointer equality).

To support the latter case, I rewrote the == and != operators for
ilist_iterator and MachineInstrBundleIterator.

  - The implicit constructors now use enable_if to exclude
    const-iterator => non-const-iterator conversions from overload
    resolution (previously it was a compiler error on instantiation, now
    it's SFINAE).

  - The == and != operators are now global (friends), and are not
    templated.

  - MachineInstrBundleIterator has overloads to compare against both
    const_pointer and const_reference.  This avoids the implicit
    conversions to MachineInstrBundleIterator that assert, instead just
    checking the address (and I added unit tests to confirm this).

Notably, the only remaining uses of ilist_iterator::getNodePtrUnchecked
are in ilist.h, and no code outside of ilist*.h directly relies on this
UB end-iterator-to-pointer conversion anymore.  It's still needed for
ilist_*sentinel_traits, but I'll clean that up soon.

Duncan P. N. Exon Smith ec30cc2171 Hexagon: Avoid dereferencing end() in HexagonCopyToCombine::findPairable
Check for end() before skipping through debug values.  This avoids
dereferencing end() when the instruction is the final one in the basic
block.  (It still assumes that a debug value will not be the final
instruction in the basic block.  No tests seemed to violate that.)

Many Hexagon tests trigger this, but they happen to magically pass right
now.  I found this because WIP patches for PR26753 convert them into
crashes.

Krzysztof Parzyszek a3386501af [Hexagon] Use integer instructions for floating point immediates
Floating point instructions use general purpose registers, so the few
instructions that can put floating point immediates into registers are,
in fact, integer instruction. Use them explicitly instead of having
pseudo-instructions specifically for dealing with floating point values.

Simplify the constant loading instructions (from sdata) to have only two:
one for 32-bit values and one for 64-bit values: CONST32 and CONST64.

Duncan P. N. Exon Smith 98226e3d93 Hexagon: Avoid implicit iterator conversions, NFC
Avoid implicit iterator conversions from MachineInstrBundleIterator to
MachineInstr* in the Hexagon backend, mostly by preferring MachineInstr&
over MachineInstr* and switching to range-based for loops.

There's a long tail of API cleanup here, but I'm planning to leave the
rest to the Hexagon maintainers.  HexagonInstrInfo defines many of its
own predicates, and most of them still take MachineInstr*.  Some of
those actually check for nullptr, so I didn't feel comfortable changing
them to MachineInstr& en masse.

Chandler Carruth b415bf98f0 This reverts a long string of commits to the Hexagon backend. These
commits have had several major issues pointed out in review, and those
issues are not being addressed in a timely fashion. Furthermore, this
was all committed leading up to the v3.1 branch, and we don't need piles
of code with outstanding issues in the branch.

It is possible that not all of these commits were necessary to revert to
get us back to a green state, but I'm going to let the Hexagon
maintainer sort that out. They can recommit, in order, after addressing
the feedback.

Reverted commits, with some notes:

Primary commit r154616: HexagonPacketizer
  - There are lots of review comments here. This is the primary reason
    for reverting. In particular, it introduced large amount of warnings
    due to a bad construct in tablegen.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154622: CMake fixes
    - r154660: Fix numerous build warnings in release builds.
  - Please don't resubmit this until the three commits above are
    included, and the issues in review addressed.

Primary commit r154695: Pass to replace transfer/copy ...
  - Reverted to minimize merge conflicts. I'm not aware of specific
    issues with this patch.

Primary commit r154703: New Value Jump.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154703: Remove iostream usage
    - r154758: Fix CMake builds
    - r154759: Fix build warnings in release builds
  - Please incorporate these fixes and and review feedback before
    resubmitting.

Primary commit r154829: Hexagon V5 (floating point) support.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154841: Remove unused variable (fixing build warnings)

There are also accompanying Clang commits that will be reverted for
consistency.
