Make more JavaScriptCore allocations use heap identifiers
https://bugs.webkit.org/show_bug.cgi?id=252104
rdar://105315215
Reviewed by Yusuke Suzuki.
When BENABLE_MALLOC_HEAP_BREAKDOWN and ENABLE_MALLOC_HEAP_BREAKDOWN are
defined, we use multiple debug heaps
with identifiers to make it easier to determine what is using memory when using
system memory tools.
Break down more of the "WebKit Using System Malloc" heap by assigning heap
identifiers to more allocations
in JavaScriptCore. These were motivated by tracking the largest uncategorized
live allocations, via
TRACK_MALLOC_CALLSTACK.
WTF_MAKE_FAST_ALLOCATED_WITH_HEAP_IDENTIFIER() is added for GetByStatus,
PutByStatus, UnlinkedCodeBlock_RareData,
UnlinkedMetadataTable, JITCodeMap, HasOwnPropertyCache and VM.
IsoAlignedMemoryAllocator gets its own DebugHeap just like
GigacageAlignedMemoryAllocator.
