24c35b92bc Revert "Reland "Remove all custom CopyCharsUnsigned implementations""
This reverts commits 9febc505bd
(along with followup commit 60624b5692).

Reason for revert: Breaks win32 nosnap shared, blocking lkgr & roll:
https://ci.chromium.org/p/v8/builders/ci/V8%20Win32%20-%20nosnap%20-%20shared/35145

nosnap bots may be deprecated, but as long as they're in LKGR
we need to mind them.

f1fb43a0ab [runtime] Remove buggy dead code path from Runtime_CreateRegExpLiteral
Runtime_CreateRegExpLiteral pretends to handle the case where we
already have a boilerplate but the code just passes an empty handle
to JSRegExp::Copy. This CL replaces the code with a CHECK that the
boilerplate doesn't exist.

A few mostly cosmetic changes along the way.

29bdb26bcb [CSA][cleanup] TNodify builtins conversion gen
One Node* remains since it is crashing when TNodified since it
has the empty Context. When this happens, it means the Context
might not be needed. In this case it's hard to see if that's the
case since it is propagated all over the place. Created a TODO
so we can solve it later, when TNodification is more complete.

e92e8871dd [wasm] Make WasmInterpreterInternals a normal object
For unknown reasons, WasmInterpreterInternals was a zone object. However
WasmInterpreterInternals indirectly owns a global handle and a
unique_ptr, both for the interpreter stack. As a zone object,
WasmInterpreterInternals is never destructed, and therefore never frees
the unique_ptr. With this CL I make WasmInterpreterInternals a normal
object and allocate it into a unique_ptr, so that it gets destructed
properly.

2172208dbc [arm64] Mark PopLowestIndexAsCode as inline
The function CPURegList::PopLowestIndex is called many times in the
arm64 simulator. However, the simulator does not need a full CPURegister
but only its register code. This CL creates a second PopLowestIndexAsCode
method which only returns the register code, and also marks the function
as inline. This speeds up the mjsunit/wasm/asm-wasm-f32 test from
1:45min to 1:35min in the optdebug build on my machine.

b8127393eb [compiler] Use PersistentMap in store-store elimination
Store-store elimination can potentially allocate many temporary data
structures, all of which are contained in its so-called temporary
zone. The zone is 'temporary' in the sense of only existing for the
lifetime of the StoreStoreEliminationPhase; but all allocated memory
remains alive until the phase terminates.

Investigation of a pathological case (see the linked bug) showed this
zone reaching a size of 4GB. The cause in this specific case was the
UnobservableSet data structure, conceptually an immutable set (i.e.
each operation creates a full copy). This CL changes the
UnobservableSet to use a PersistentMap backing store rather than a
ZoneSet. PersistentMap is intended for exactly this use-case, since
copies are basically free and updates only change small parts of the
data structure.

Memory consumption for the linked pathological case drops from 4GB to
70MB and execution speeds up from 20s to 17s.

167a89469d [heap] Split old-to-new remembered set
Split OLD_TO_NEW remembered set and add OLD_TO_NEW_SWEEPING. The
OLD_TO_NEW remembered set is moved to OLD_TO_NEW_SWEEPING during
mark-compact. OLD_TO_NEW_SWEEPING is then modified by the sweeper.
Before using the page again, OLD_TO_NEW and OLD_TO_NEW_SWEEPING are
merged again.

This means only the main thread modifies OLD_TO_NEW, the sweeper only
removes entries from OLD_TO_NEW_SWEEPING. We can use this property
to make accesses non-atomic in a subsequent CL.
