JavaScriptCore ASan build fails due to weak external symbol:

PhaseScriptExecution Check For Weak VTables and Externals
ERROR: JavaScriptCore has a weak external symbol in it (/Volumes/Data/BuildSlave/Monarch-WebKitASan/build/OpenSource/WebKitBuild/Debug-iphonesimulator/JavaScriptCore.framework/JavaScriptCore)
ERROR: A weak external symbol is generated when a symbol is defined in multiple compilation units and is also marked as being exported from the library.
ERROR: A common cause of weak external symbols is when an inline function is listed in the linker export file.
ERROR: symbol __ZNK3JSC8JSObject19ordinaryToPrimitiveEPNS_9ExecStateENS_22PreferredPrimitiveTypeE

This regressed with:
