Final Mac rebaseline attempt for r146531 since r146564 wasn't enough.

I'm sorry I made a huge mess here.

Leak bots erroneously report JSC::WatchpointSet as leaking
https://bugs.webkit.org/show_bug.cgi?id=107781

Reviewed by Filip Pizlo.

Since leaks doesn't support tagged pointers, avoid using it by flipping the bit flag to indicate
the entry is "fat". We set the flag when the entry is NOT fat; i.e. slim.

Replaced FatFlag by SlimFlag and initialized m_bits with this flag to indicate that the entry is
initially "slim".

* runtime/SymbolTable.cpp:
(JSC::SymbolTableEntry::copySlow): Don't set FatFlag since it has been replaced by SlimFlag.
(JSC::SymbolTableEntry::inflateSlow): Ditto.

* runtime/SymbolTable.h:
(JSC::SymbolTableEntry::Fast::Fast): Set SlimFlag by default.
(JSC::SymbolTableEntry::Fast::isNull): Ignore SlimFlag.
(JSC::SymbolTableEntry::Fast::isFat): An entry is fat when m_bits is not entirely zero and SlimFlag
is not set.

(JSC::SymbolTableEntry::SymbolTableEntry): Set SlimFlag by default.
(JSC::SymbolTableEntry::SymbolTableEntry::getFast): Set SlimFlag when creating Fast from a fat entry.
(JSC::SymbolTableEntry::isNull): Ignore SlimFlag.
(JSC::SymbolTableEntry::FatEntry::FatEntry): Strip SlimFlag.
(JSC::SymbolTableEntry::isFat): An entry is fat when m_bits is not entirely zero and SlimFlag is unset.
(JSC::SymbolTableEntry::fatEntry): Don't strip FatFlag as this flag doesn't exist anymore.
(JSC::SymbolTableEntry::pack): Preserve SlimFlag.

(JSC::SymbolTableIndexHashTraits): empty value is no longer zero so don't set emptyValueIsZero true.
