Summary:
Convert all obvious node_begin/node_end and child_begin/child_end
pairs to range based for.
Sending for review in case someone has a good idea how to make
graph_children able to be inferred. It looks like it would require
changing GraphTraits to be two argument or something. I presume
inference does not happen because it would have to check every
GraphTraits in the world to see if the noderef types matched.
Note: This change was 3-staged with clang as well, which uses
Dominators/etc from LLVM.

The previously used "names" are rather descriptions (they use multiple
words and contain spaces), use short programming language identifier
like strings for the "names" which should be used when exporting to
machine parseable formats.
Also removed a unused TimerGroup from Hexxagon.

The NamedRegionTimer initializer without a group name puts the Timer
into the "Misc" group and is (nearly) unused. Remove it.
The only user of this constructor appears to be the HexagonGenInsert pass,
which creates a counter without group to count the complete execution
time of that pass, however since every pass gets a counter by the
PassManager anyway this should be unnecessary. Also removed the
pointless TimerGroup there.

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.

(Const)?MIOperands is equivalent to the C++ style
MachineInstr::mop_iterator. Use the latter for consistency except for a
few callers of MIOperands::analyzePhysReg().

Update APIs in MachineInstrBundle.h to take and return MachineInstr&
instead of MachineInstr* when the instruction cannot be null. Besides
being a nice cleanup, this is tacking toward a fix for PR26753.

Remove some unnecessary explicit special members in Hexagon that, once
removed, allow the other implicit special members to be used without
depending on deprecated features.
