This moves all the machinery for tracing inlined function that is
specific to Crankshaft into the appropriate component. Only the old
side-channel via a list of InlinedFunctionInfo structs remained within
the CompilationInfo for now. In the long run we will reconstruct that
information from the deoptimization data on the code objects.

This changes different locations to extract the reference to the wasm
object and the function index from the stack trace, and make it
available through all the APIs which process stack traces.
The javascript CallSite object now has the new methods isWasm(),
getWasmObject() and getWasmFunctionIndex(); the byte offset is
available via getPosition().

Function names of wasm frames should be fully functional with this
commit, position information works reliably for calls, but not for
traps like unreachable or out-of-bounds accesses.

Revert of [turbofan] Take the immediate size in account when narrowing ia32/x64 word comparison operators. (patchset #2 id:20001 of https://codereview.chromium.org/1948453002/ )

Reason for revert:
Breaks WASM; please also add tests when relanding.

Original issue's description:
> [turbofan] Take the immediate size in account when narrowing ia32/x64 word comparison operators.

> Before this patch, we would emit a cmp or test with a memory operand only if both of the operands in the IR were loads. Now if either of them is a load and the other one is an immediate, we can use a memory operand if the load representation machine size is wide enough to represent the latter.

This operator was initially designed to handle arbitrary effect merging
for effect relaxation, but we don't do that (at least currently). So no
need to keep the dead operator around.

Scope analysis is over-conservative when treating variable resolutions
as possibly-shadowed by a sloppy eval. In the attached bug, this comes
into play since catch scopes have different behavior with respect to
the "calls eval" in eager vs lazy compilation (in the latter, they
are never marked as "calls eval" because CatchContexts don't have
an associated ScopeInfo).

This patch changes the scope-type check to also eliminate a few other
cases where shadowing isn't possible, such as non-declaration block scopes.

A load instruction will implicitely clear the top 32 bits when writing to a W
register. This patch avoids generating a `mov` instruction to zero-extend the
result in this case.

For example, this occurs in the generated code for dispatching to the next
bytecode in the interpreter:

  kind = BYTECODE_HANDLER
  name = LdaZero
  compiler = turbofan
  Instructions (size = 36)
  0x32e64c60     0  add x19, x19, #0x1 (1)
  0x32e64c64     4  ldrb w0, [x20, x19]
  0x32e64c68     8  mov w0, w0
                    ^^^^^^^^^^
  0x32e64c6c    12  lsl x0, x0, #3
  0x32e64c70    16  ldr x1, [x21, x0]
  0x32e64c74    20  movz x0, #0x0
