Dan Gohman c968297b95 [WebAssembly] Update opcode values according to recent spec changes.
This corresponds to the "0xd" opcode renumbering.

Michael Kuperstein 2bc3d4d46c [SelectionDAG] Rename fextend -> fpextend, fround -> fpround, frnd -> fround
The names of the tablegen defs now match the names of the ISD nodes.
This makes the world a slightly saner place, as previously "fround" matched
ISD::FP_ROUND and not ISD::FROUND.

Dan Gohman fb3e0594e4 [WebAssembly] Use a physical register to describe ARGUMENT liveness.
Instead of trying to move ARGUMENT instructions back up to the top after
they've been scheduled or sunk down, use a fake physical register to
create a liveness constraint that prevents ARGUMENT instructions from
moving down in the first place. This is still not entirely ideal, however
it is more robust than letting them move and moving them back.

Dan Gohman 1031d4a8c3 [WebAssembly] Use tabs instead of spaces in assembly output.
This seems to be the most popular convention among the other backends.

Dan Gohman bc58a7bad0 [WebAssembly] Un-mangle the conversion instruction names.
This arranges the types in the LLVM instruction names in the same order that
they appear in the WebAssembly opcode names, and eliminates
double-underscores.

Dan Gohman af29bd4fd4 [WebAssembly] Add AsmString strings for most instructions.
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.

Dan Gohman dc51b96b7f [WebAssembly] Implement the remaining conversion operations.
This is a temporary assembly syntax that will likely evolve along with
broader upcoming syntax changes.

JF Bastien 5ca0baca4a WebAssembly: basic instructions todo, and basic register info.
Summary:
This code is based on AArch64 for modern backend good practice, and NVPTX for
virtual ISA concerns.
