may not be used to initialize i64-typed globals. The existing
code for doing that relied on UB; since it's a spec violation
the fix is to throw instead.

This CL builds on top of feedback preprocessing. It brokerizes
all parts of element access reduction and disallows heap access there
(except for debug tracing).
To make this work without breaking tests (when concurrent inlining is
enabled):
- We don't inline functions that weren't serialized for compilation.
- We don't optimize for constant typed-array receivers when the typed
array wasn't serialized.
This means that from now on --concurrent-inlining (and thus --future)
may result in less optimization than the default configuration.

When VTune JIT support is enabled, the WasmEngine of an Isolate tries to
enable code logging by EnableCodeLogging() method. This multithreaded
method requires a Mutex for safety. However, as the WasmEngine is not
created, the Mutex of it is not initialized. An attempt of acquiring
this Mutex results in an error. The bug is fixed by creating WasmEngine
before it enables code logging.

Original Commit Message:
Refactor the CallApiCallback builtin to
- pass the context as with other stubs, and
- pass holder and call data in registers.
This avoids having to place holder and call data onto the stack, and
thus makes it possible to easily call the CallApiCallback builtin from
other builtins while just forwarding the (stack) arguments. The idea
is to use this in the future to optimize the general case of calling
into any API method via a FunctionTemplateInfo and doing appropriate
security and/or interface checks upfront as necessary (eventually making
the HandleApiCall C++ builtin obsolete at some point).
