[wasm] Int64Lowering of I64Shl on ia32.
...
I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new
operator takes 3 inputs, the low-word input, the high-word input, and
the shift, and produces 2 output, the low-word output and the high-word
output.
At the moment I implemented the lowering only for ia32, but I think the
CL is already big enough. I will add the other platforms in separate
CLs.

[wasm] Int64Lowering of FXXXConvertI64 instructions.
...
On 32-bit systems FXXXConvertI64 instructions are compiled to calls to
C functions. The TF node for the function call is already generated in
the wasm compiler, the lowering of the I64 parameter is done in the
Int64Lowering.

[wasm] I added comparison operators to the Int64Lowering.
...
Comparison operators are lowered using to a lexicographic ordering, e.g.
(a,b) <= (c,d) <<>> (a < c) | (a == c) & (b <= d).
