Reland "[Interpreter] Do not use IC slots for property load/stores in an IIFE and top-level code" This is a reland of 690bda84eb023c7afa63c51131c474771fbf7bda Original change's description: > [Interpreter] Do not use IC slots for property load/stores in an IIFE and top-level code > > An IIFE or top-level code is executed only once hence, there is no need to collect > type feedback. We can save some memory by not using IC slots for property Loads/Stores > within a IIFE/top-level code. This CL emits Runtime Get/Set property calls instead of LdaNamedProperty > /StaNamedProperty for the property loads within a IIFE and top-level code. > > Change-Id: I3e0ce26d05d82bb3648cb9262c4e112a2c4556c9 > Reviewed-on: https://chromium-review.googlesource.com/1146579 > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > Reviewed-by: Marja Hölttä <marja@chromium.org> > Reviewed-by: Camillo Bruni <cbruni@chromium.org> > Reviewed-by: Yang Guo <yangguo@chromium.org> > Commit-Queue: Chandan Reddy <chandanreddy@google.com> > Cr-Commit-Position: refs/heads/master@{#54949} Change-Id: I7b07ce86f7236d82191caaceafd31b86e5863ff5 Reviewed-on: https://chromium-review.googlesource.com/1167802 Reviewed-by: Camillo Bruni <cbruni@chromium.org> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Yang Guo <yangguo@chromium.org> Reviewed-by: Toon Verwaest <verwaest@chromium.org> Commit-Queue: Chandan Reddy <chandanreddy@google.com> Cr-Commit-Position: refs/heads/master@{#55017}
