This improves type safety and is less verbose. Use SimpleTy only where
an integer is needed like switches or emitting a VBR.

Print the source location of the instruction definition in comment next
to the enum value for each instruction. To make this more readable,
change formatting of the instruction enums to be better aligned.
Example output:
```
VLD4qWB_register_Asm_8 = 573, // (ARMInstrNEON.td:8849)
VMOVD0 = 574, // (ARMInstrNEON.td:6337)
VMOVDcc = 575, // (ARMInstrVFP.td:2466)
VMOVHcc = 576, // (ARMInstrVFP.td:2474)
VMOVQ0 = 577, // (ARMInstrNEON.td:6341)
```

I believe it became no-op with the removal of the "positionally encoded
operands" functionality (b87dc356 is the last commit in the series).
There are no changes in the generated files.

|
Also change its name to start with a lowercase letter and update
the doxygen comment to conform to the coding standard.

- Change `hadOperandNamed` to return index as std::optional and rename
it to `findOperandNamed`.
- Change `SubOperandAlias` to return std::optional and rename it to
`findSubOperandAlias`.

`CGIOperandList::OperandInfo` (#140625)
- Change `Name`, `SubopNames`, `PrinterMethodName`, and
`EncoderMethodNames` to be stored as StringRef.
- Also changed `CheckComplexPatMatcher::Name` to StringRef as a fallout
from the above.
Verified that all the tablegen generated files within LLVM are
unchanged.

Also use brace initialization and emplace to avoid explicitly
constructing std::pair, and the same for std::tuple.

This is a part of effort to have better const correctness in TableGen
backends:

- Fix include guards for headers under utils/TableGen to match their
paths.
|
|
Refactor of the llvm-tblgen source into:
- a "Basic" library, which contains the bare minimum utilities to build
`llvm-min-tablegen`
- a "Common" library which contains all of the helpers for TableGen
backends. Such helpers can be shared by more than one backend, and even
unit tested (e.g. CodeExpander is, maybe we can add more over time)
Fixes #80647
