Add comments explaining how to iterate over an OrderedHashTable.
Use the correct strategy for iteration in Set::AsArray().
Add a DCHECK bounds check in OrderedHashTable::KeyAt().

Currently we have Time and TimeTicks sharing some methods. This patch
creates TimeBase, and makes Time and TimeTicks inherits from it, so that time
related classes won't have to implement common methods and it's easier to
introduce new time related classes.

Some tests which fail with '--ignition --turbo --turbo-from-bytecode' pass with
just '--ignition'. Unskip these tests. Also group other tests with related
bugs.

callstats.html in combination with callstats.py can be used to get an in-depth
view on where we spend time in v8. Furthermore, with callstats.html we can
compare different versions of v8/chrome and see where and how performnce
evolved.
Drive-by-fix: add missing copyrights header to ic-explorer.html and format

This removes:
- PersistentBase::SetWeak that takes WeakCallbackData.
The embedders should use the version that takes WeakCallbackInfo.
- PersistentBase::SetPhantom.
The embedders should SetWeak that takes WeakCallbackInfo.
Functions in DefaultPersistentValueMapTraits are changed to accept
WeakCallbackInfo instead of WeakCallbackData.

Hydrogen logs are ambiguous if multiple functions share the same name.
This change adds file names to this output. Functions are now named
<file_name>:<function_name> to reduce this ambiguity.

- Cleanup CL to remove unused parameters in elements.cc. Additionally use fields
from the KeyAccumulator wherever possible.

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.

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.
