Summary:
There are a few instructions that all map to the same opcode, so
when disassembling, we have to pick one. That was just the first one
before (the except_ref variant in the case of "call"), now it is the
one marked as IsCanonical in tablegen, or failing that, the shortest
name (which is typically the "canonical" one).
Also introduced a canonical "end" instruction for this purpose.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Replace its functionality with a TableGen InstrInfo relational
instruction mapping. Although arguably more complex than the TableGen
backend, the relational mapping is a smaller maintenance burden than a
TableGen backend.

Summary:
- Categorize instructions into the categories as in the SIMD spec
- Move SIMD-related definition to WebAssemblyInstrSIMD.td
- Put definition and use of patterns together
- Add newlines here and there

WebAssemblyInstrFormats.td retains only multiclasses that are used in
multiple other tablegen files.

Summary:
This CL adds support for arbitrary BUILD_VECTORS, i.e. not splats and
not consts. This is the last feature needed to properly lower v2i64
multiplies without a i64x2.mul instruction (which is not in the spec),
so i64x2.mul is removed as well.

Remove unnecessary condition and fix whitespace

Summary:
One for register based, much like the existing definitions,
and one for stack based (suffix _S).
This allows us to use registers in most of LLVM (which works better),
and stack based in MC (which results in a simpler and more readable
assembler / disassembler).
Tried to keep this change as small as possible while passing tests,
follow-up commit will:
- Add reg->stack conversion in MI.
- Fix asm/disasm in MC to be stack based.
- Fix emitter to be stack based.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Mangling type information into MachineInstr opcode names was a temporary
measure, and it's starting to get hairy. At the same time, the MC instruction
printer wants to use AsmString strings for printing. This patch takes the
first step, starting the process of adding AsmStrings for instructions.
