This introduces unreachable state into load elimination. We mark state
as unreachable if we know statically that a map check would fail.
When processing effect phis, we disconnect unreachable state's
control from the effect phi's merge, and point it to RuntimeAbort.
The control input to the merge is then updated with Dead. Dead
code elimination prunes the merge, phis and effect phis.

Implicitly escape all output that is passed to Log::MessageBuilder.
We escape non-printable characters and the log field separator ','
using the \x00 and \u0000 escape sequences.

Example:
Before: event-foo,"space: ","comma: ,","double quotes: """
After:  event-foo,space: ,comma: \x2C,double quotes: "

This might slightly impact human readability of the log files in
extreme cases. However, most strings do not contain any escaped
characters.

The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:

    Array.prototype.sort.call(null, 1);

Behavior before applying the patch (incorrect message):

    TypeError: Array.prototype.sort called on null or undefined

Expected behavior:

    TypeError: The comparison function must be either a function or
               undefined

This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.

The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

- Caveat of this CL: Checked casts (CAST()) are not possible for

Arm64's implementation of `TurboAssembler::Abort()` supports printing the
bailout reason to the standard output without calling to the runtime. For this
to work, we need access to the host's printf function so we can call it
directly. In the general case, `Abort` does call the runtime, however, we cannot
do it if we want to abort from inside CEntryStub.

In the special case of KeyedLoadIC, where the key that is passed in is a
Name that is always the same we only checked for identity in both the
stub and the TurboFan case, which works fine for symbols and internalized
strings, but doesn't really work with non-internalized strings, where
the identity check will fail, the runtime will internalize the string,
and the IC will then see the original internalized string again and not
progress in the feedback lattice. This leads to tricky deoptimization
loops in TurboFan and constantly missing ICs.

This adds fixes the stub to always try to internalize strings first
when the identity check fails and then doing the check again. If the
name is not found in the string table we miss, since in that case the
string cannot match the previously recorded feedback name (which is
always a unique name).

In TurboFan we represent this checks with new CheckEqualsSymbol and
CheckEqualsInternalizedString operators, which validate the previously
recorded feedback, and the CheckEqualsInternalizedString operator does
the attempt to internalize the input.

This CL provides the basic infrastructure on the GC side for write protected code pages.

The only thing missing on the GC side is the out-of-line free list implementation. In this
CL sweeper threads and the mutator need to synchronize when page protection mode changes.
This would not be necessary if the sweepr use and out-of-line free list.

Code allocation is currently protected by a CodeSpaceMemoryModificationScope. This may
go away with a unification of code space allocation and initialization that will happen
later.

One thing missing in this CL: freshly added pages are still read+write+executable. This
also needs to change: WIP
