[JSC] Not using PolymorphicAccess in Handler IC
https://bugs.webkit.org/show_bug.cgi?id=278283
rdar://134159625
Reviewed by Yijia Huang.
Handler IC is already keeping AccessCase information in handlers. Thus
PolymorphicAccess is unnecessary abstraction.
This patch refactors the architecture so that we no longer have
PolymorphicAccess in Handler IC. Once FTL moves to Handler IC,
64bit IC will completely remove PolymorphicAccess, using chain of handlers.
