This CL adds "new.target" to the ScopeObject with the materialized
stack local variables. It's only available if the parser actually
allocates a variable for it, otherwise we currently throw a
ReferenceError.
The added test also ensures that "new.target" is only included for
debug-evaluate, but NOT for the scope view. Having ".new.target"
show up there would be more confusing than helpful.
Drive-by: Remove bogus DCHECK. The context we try to lookup
"new.target" can be anything, not just a `with` context.

We were moving the char_code value into a scratch register before calling StringFromCharCode, in case it aliases the result register and
is clobbered by result allocation.
However, there is also a fast direct jump into StringFromCharCode for
one-byte strings. This jump will jump over the move into the scratch
register.
Instead, pass the scratch register into StringFromCharCode explicitly,
and let it do the moving of the char_code where necessary.
Additionally, move around some debug code asserts to increase their
coverage.

Rather than encoding clobbering with a separate reglist, use the
concept of being "free and blocked" for clobbering. This makes sure that
clobbered registers are not used in later input allocations, and that
two clobbering inputs don't alias. Probably in the future we want to
process clobbering inputs first, before non-clobbering ones, to make
sure that no clobbering input can alias a non-clobbering input (even if
the non-clobbering input is an earlier one).
Also add some documentation to RegisterFrameState to explain these
different states.

This CL partially reverts https://crrev.com/c/2731527.
When we bootstrap a new context we need to force instantiate lazy
accessors so the debugger is able to set breakpoints on them.
Normally this happens automatically when we instantiate function
templates that have the "BreakAtEntry" bit set on them, but context
snapshots are just deserialized.
This means we need to do a heap walk and instantiate any lazy
accessor that we find and install the `DebugBreakTrampoline` should
the accessor require it.
Note that we keep the fix from the original CL: Instantiate
accessors only once and keep using that JSFunction.

optimized, and will always require tier-up via intrinsics.
This prevents variants with low interrupt budgets from messing with
tests that are carefully controlling optimization state across
multiple optimisations, as well as simplifying the mechanism since we
no longer have to maintain the state machine of 'function state'.

V8 implements accessors defined in C++ via FunctionTemplates in a lazy
manner. When userland JS uses the accessor, V8 calls the corresponding
C++ code directly. Only when the user JS obtains a reference to the
function object itself (e.g. via Reflect.getOwnPropertyDescriptor) does
V8 instantiate a JSFunction object.
This makes breakpoint logic tricky. The debugger requires a JSFunction
when the user wants to set a breakpoint on such an accessor.
There is already some logic in place that forces instantiation of
accessors with a breakpoint on them.
Unfortunately that logic forgot to also install the
"DebugBreakTrampoline" on the instantiated JSFunction that will
actually pause execution. This CL fixes that.
Note that this is not the whole fix. Contexts deserialized from
snapshots need a heap walk that also forces instantation of the
accessors.

`LoadMap` calls `Load` and `Int32Constant`, which are machine
operators. While doing this in the frontend is somewhat supported, it
should be protected with EnterMachineGraph/ExitMachineGraph. So far
this doesn't seem to have broken anything, but we're not confident
that this will always work.
Rather than going through the complexity adding the
Enter/ExitMachineGraph nodes, I've removed the LoadMap to use a simple
LoadField instead.

Std hash tables where keys are HeapObjects which can be both Code and
non-Code objects must use Object::KeyEqualSafe equality comparator.
