While working on the Torque compiler, I've sometimes found it difficult
to understand Torque's intermediate representation and how it
corresponds to the output. In this change, I propose adding a build flag
that instructs Torque to emit comments describing its IR, interspersed
in the generated code. This is particularly useful for seeing the stack
management instructions (Peek, Poke, and DeleteRange) which don't emit
any corresponding C++ code.

Processing StateValues into operands is one of the most costly
parts of instruction selection. As it happens, StateValues are
shared by many nodes, and so we are unecessarily reprocessing
the same StateValues multiple times. This CL introduces caching
for the processed StateValues enabling very fast emitting of
operands for subsiquent instructions with the same StateValue.
The hitrate for the cache is higher than 90% on most optimizations.

Liftoff defines many signatures of fixed size. This is currently done by
defining a fixed-size array on the stack, and then using this in the
signature definition. This is cumbersome and hard to read, since the
array contains return types and parameter types, and only the signature
definition separates the two. But also the order of those two sizes in
the signature is non-obvious and easy to get wrong.
This CL introduces a helper to define fixed-size signatures in a
"builder style", i.e. parameters and return types can be added
separately. The fixed-size array will be contained in the returned
class, so it will still be stack-allocated like before. The copies to
iteratively build up this array should be completely eliminated by the
compiler, so the binary code should look exactly the same.

include ({store}, {load}) pairs which both have integral representation

Splitting a range at an instruction position can lead to incorrect code
generation. See the attached bug for a concrete example of that, in
particular comment 6.
The issue is when we add a gap move to connect the split ranges during
the ConnectLiveRanges phase. If the split position is a gap position,
the move coincides with the start of the range. But if the split
position is an instruction position, the move is inserted in the last
gap position, which is outside of the range. This violates assumptions
made during the main register allocation phase and can invalidate the
use of that register in a different range.
The fix proposed here works by moving the split position backwards to
the previous gap position. This ensures that the connecting gap move is
always at the start of the range that it defines.

Some ValueKinds were defined based on the size of a system pointer or
the size of a tagged value. In order to be able to reuse those
definitions in both LiftoffAssembler and LiftoffCompiler, define them as
public constants on LiftoffAssembler.
Also, avoid the "ValueType" suffix, since they are not ValueTypes, but
ValueKinds.

In contrast to wasm modules, asm.js modules have an empty source URL.
Thus loosen a DCHECK and handle the nullptr source_url correctly.
Also add regression tests that check that we don't crash. Those can
later be extended to check that the profile looks as expected; for now
they only check that we terminate.

This is done with a script that does something like:
files=$(ag 'v\d\d?x\d\d?[._]?all_?true' -l)
sed -i 's/V\(8x16\|16x8\|32x4\|64x2\)\([._]\?\)\([aA]ll_\?[tT]rue\)/I\1\2\3/g' $(files)
sed -i 's/v\(8x16\|16x8\|32x4\|64x2\)\([._]\?\)\([aA]ll_\?[tT]rue\)/i\1\2\3/g' $(files)
And manual fixups in test-run-wasm-simd.cc and wasm-opcodes-inl.h.

They were using a fixed offset of pc+2, but since the instructions can
be multiple bytes long (leb128 encoded), it should be using *len.
Drive-by fix to add missing instructions to wasm-module-builder.js.
