972e226543 [base] Fix bugs in AllocateInternal on Fuchsia
This CL fixes two issues:

1) When the specified vmar_offset was zero, the previous logic would
   incorrectly conclude that no target address was specified, and would
   potentially place the allocation elsewhere in memory, not at the
   desired address. This CL now passes both the target address and the
   VMAR base address to AllocateInternal, which can then correctly
   determine whether a target address was supplied.

2) When the root_vmar was used and a hint specified, the previous logic
   would incorrectly use nullptr as base address of the root_vmar, which
   appears to be incorrect. The new logic now obtains the actual base
   (apparently 2MB) through zx_object_get_info during initialization.

1f53cbf197 [inspector] Add Runtime#getExceptionDetails CDP method
CDP has a "ExceptionDetails" structure that is attached to various
CDP commands, e.g. "Runtime#exceptionThrown" or "Runtime#evaluate".
The stack trace in the "ExceptionDetails" structure is used in
various places in DevTools. The information in the "ExceptionDetails"
structure is extracted from a v8::Message object. Message objects
are normally created at the exception throw site and may augment
the error with manually inspecting the stack (both to capture a fresh
stack trace in some cases, as well as to calculate location info).

The problem is that in some cases we want to get an "ExceptionDetails"
structure after the fact, e.g. when logging a JS "Error" object in
a catch block. To help in this case, this CL introduces a new
CDP method "Runtime#getExceptionDetails" that behaves exactly as
advertised: It provides a populated "ExceptionDetails" structure
from a JS Error object.

757830b02b [Torque] Generalize Torque literals to larger size

This CL replaces the old literal expression with an integer and
floating point literal expression that are unbounded in size. We
allow implicit conversion of these literals to arbitary integer
and floating point types respectively and insert a corresponding
bounds check into generated CSA.

c992a25635 [base] Add VirtualAddressSpace unittests
These tests cover the basic VirtualAddressSpace functionality for the
three different types of address spaces currently available: the root
space, subspaces, and emulated subspaces.

This CL also includes minor bugfixes in VirtualAddressSpace
implementations and removes RandomizedVirtualAlloc in platform-win32.cc
which doesn't seem to do anything useful anymore but prevents page
allocation hints from working correctly.

c7fbac6a72 Handles: Fix OnStackTracedNodeSpace with -fsanitize=safe-stack
When the stack is split in safe and unsafe parts, on-stack
TracedReferences are allocated on the unsafe stack. What currently
happens is that on GC we destroy all the on-stack references below the
current frame of the *safe* stack. If the safe stack is allocated above
the unsafe counterpart, then all the traced references will be
preliminary destructed on GC. This CL fixes it by using
__builtin___get_unsafe_stack_ptr() if -fsanitize=safe-stack is enabled.

In addition, deduplicate OnStackTracedNodeSpace::IsOnStack() and
Stack::IsOnStack() and move more logic into ::heap::base::Stack.

80bbbb143c [class] handle existing readonly properties in StoreOwnIC
Previously, StoreOwnIC incorrectly reuses the [[Set]] semantics
when initializing public literal class fields and object literals in
certain cases (e.g. when there's no feedback).
This was less of an issue for object literals, but with public class
fields it's possible to define property attributes while the
instance is still being initialized, or to encounter existing static
"name" or "length" properties that should be readonly. This patch
fixes it by

1) Emitting code that calls into the slow stub when
   handling StoreOwnIC with existing read-only properties.
2) Adding extra steps in StoreIC::Store to handle such stores
   properly with [[DefineOwnProperty]] semantics.

4ebc9b7b0d Reland "[runtime] Adds LocalNameIterator"

Adds a GC safe (using handles) and unsafe versions of the iterator.

V8HeapExplorer needs an unsafe one, since it does not allow the
creation of handles.

It serves as a prototype to check if such an API is suitable for
improving stack traces for frameworks which split up tasks across
multiple frames, yielding back to the main thread when some time budget
is consumed.

JS stack) script name or sourceURL. Currently, API clients will
collect multiple stack traces in increasing sizes to accomplish the
same goal. The new method walks the JS stack in the same way as the
stack trace collection mechanic but doesn't create/allocate stack info
or callsite objects along the way.
