5966276d56 Change deprecated semantics of function template signatures. 
This changes how FunctionTemplate interprets a Signature that specifies
compatible receivers and arguments. Only the hidden prototype chain will
be considered when searching for compatible receivers. This prevents
JavaScript from modifying the inheritance relationship set up by the
embedder.

d5f589808d Removed a bunch of GetExistingThreadLocal calls by threading the Isolate. 
For Octane, the number of calls go down from 7341629 to 1947880, i.e. they are
reduced by more than 73%. TLS access is not especially cheap, so this exercise
seems worthwhile.

3b5a6ef2e7 Removing LookupTransition from LookupRealNamedProperty and related utility functions. 
Callsites now have to manually lookup transitions if required. This
avoids unnecessary overhead of looking up transitions when we don't need
them. This also allows us to use IsFound() in many places where
IsProperty() was required previously.

9e4fbb45c1 One Zone per CompilationInfo. 
The CompilationInfo record now saves a Zone, and the compiler pipeline
allocates memory from the Zone in the CompilationInfo.  Before
compiling a function, we create a Zone on the stack and save a pointer
to that Zone to the CompilationInfo; which then gets picked up and
allocated from.

fd2731a7e6 Replaced LookupResult::IsProperty by LookupResult::IsFound where possible. 
Yak shaving for map sharing with accessor properties contd.: When CALLBACKS can
have map transitions, simply looking at the property type is not sufficient
anymore to decide if a property is there or not. One has to look at the actual
contents of the descriptor entry then, but this breaks down sometimes when the
lookup is being done with a NULL holder. Luckily enough, we can oftren replace
IsProperty by the simpler IsFound, because we inspect the type immediately
afterwards, anyway.
