Wasm compilation units got smaller and smaller with recent refactorings
(https://crrev.com/c/1587386, https://crrev.com/c/1587387,
https://crrev.com/c/1587388, plus previous CLs).
They now only store a function index and the requested compilation
tier. Hence there is no reason any more to heap-allocate them.
This CL changes the compilation unit queues and interfaces to store and
pass compilation units by value. Methods that could return an empty
{unique_ptr} before are now returning a {base::Optional}.

TraceIC always expects a valid feedback vector to check for state
transitions. With lazy feedback allocations, it is possible that we don't
have feedback vectors. This cl fixes TraceIC to also work when there is no
feedback vector.

    New enum RelocInfo::COMPRESSED_EMBEDDED_OBJECT created to support
    compressed pointers in generated code. Enum name EMBEDDED_OBJECT

    RelocInfo::[set_]target_object() abstract away the difference between

    Compressed embedded objects can only be created at this time on
    x64 with pointer compression turned on. Arm64 constant pools don't

Relative code targets are emitted as pc-relative jumps. The
relocation delta must be subtracted (not added) from the branch
offset.

Before GC:

After GC:

This CL refactors WasmTableObject::Grow to make it usable for the
table.grow instruction of WebAssembly.

The refactored version of WasmTableObject::Grow does additionally:
* Check if growing is possible
* Grow the FixedArray backing store of the table and initialize the new
  fields.
* Calculate the return value of WasmTableObject::Grow.

Instead, use std::sort and std::stable_sort at the 3 (!) call sites
directly. This also removes the weird comparer adaptors from Vector,
which are only used in ZoneList.

Instead provide an abstraction that makes it hard to forget
dealing with unreliable maps.

This also fixes a deopt loop in Function.prototype.bind and
one in Array.prototype.reduce.

Ignore the error type in {assertThrows} only if it was not passed as an
argument. If users do not care about the error type they can user the
generic type {Error}. Before this change, an undefined error type would
simply be ignored. A simple typo could therefore disable the error type
assertion without being recognized.

Failure addressed by not exposing the new test to the jitless environment.
(jgruber@ on TBR).

New enum RelocInfo::COMPRESSED_EMBEDDED_OBJECT created to support
compressed pointers in generated code. Enum name EMBEDDED_OBJECT
changed to FULL_EMBEDDED_OBJECT.

RelocInfo::[set_]target_object() abstract away the difference between
FULL_EMBEDDED_OBJECT and COMPRESSED_EMBEDDED_OBJECT.

Compressed embedded objects can only be created at this time on
x64 with pointer compression turned on. Arm64 constant pools don't
support compressed objects at this time.

Original Commit Message:

    Our {Vector} template provides both {start} and {begin} methods. They
    return exactly the same value. Since the {begin} method is needed for
    iteration, and is also what standard containers provide, this CL
    switches all uses of the {start} method to use {begin} instead.

    Patchset 1 was auto-generated by using this clang AST matcher:
        callExpr(
            callee(
              cxxMethodDecl(
                hasName("start"),
                ofClass(hasName("v8::internal::Vector")))
            ),
            argumentCountIs(0))

    Patchset 2 was created by running clang-format. Patchset 3 then
    removes the now unused {Vector::start} method.
