In case of LAP(lazy accessor pair), the function's creation context must be equal to the accessor holder's creation context, so this CL changes the current context to the accessor holder's creation context. Note that this is the second attempt after https://crrev.com/2770003002 The change from the previous attempt is to skip looking for the object's constructor if the object itself is a function. Also some of Blink's LAP-context-sensitive tests got updated at https://crrev.com/c/597990 and the rest of the tests will get temporarily disabled at https://crrev.com/c/605408 .

The CallApiCallbackStub can avoid loading undefined in case the call_data is already undefined, which doubles the number of versions of the stub and adds unnecessary complexity (at the benefit of saving one stupid load). The idea is to turn the CallApiCallbackStub into a single builtin instead, which does the right thing, so this is the first step towards that goal.

This is a first step towards moving Turbofan code generation off the main thread. Summary of the changes: - AssemblerBase no longer has a pointer to the isolate. Instead, its constructor receives the few things that it needs from the isolate (on most architectures this is just the serializer_enabled flag). - RelocInfo no longer has a pointer to the isolate. Instead, the functions that need it take it as an argument. (There are currently still a few that implicitly access the isolate through a HeapObject.) - The MacroAssembler now explicitly holds a pointer to the isolate (before, it used to get it from the Assembler). - The jit_cookie also moved from AssemblerBase to the MacroAssemblers, since it's not used at all in the Assemblers. - A few architectures implemented parts of the Assembler with the help of a Codepatcher that is based on MacroAssembler. Since the Assembler no longer has the isolate, but the MacroAssembler still needs it, this doesn't work anymore. Instead, these Assemblers now use a new PatchingAssembler.

The reasons are: 1) Type feedback vectors are not shared between different native contexts and therefore the IC handler created for one native context will not be reused in other native context. 2) Access rights revocation is not supported at all, therefore given (1) once we pass the access check we don't have to check access rights again.

This CL also cleans up related interface descriptors: 1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is renamed to StoreTransitionDescriptor. 2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers cleanup will be addressed in a separate CL). These two stub ports have to be combined in one CL because: 1) without changing the StoreTransitionDescriptor TF was not able to compile them on ia32/x87 (because of lack of registers), 2) it was not possible to change the descriptor first because Crankshaft was not able to deal with the stack allocated parameters in case of a stub failure.
