The previous code assumed that trap handling was a global concept, defined
by function trap_handler::UseTrapHandler(). This CL does the first step
in changing the decision to be specifiable at a module level.
Therefore trap_handler::UseTrapHandler() is replaced by
trap_handler::IsTrapHandlerEnabled(), and communicates if compilation
supports the use of trap handlers (but still allowing the use of
bounds checking on memory accesses).
It then refactors the classes ModuleEnv and WasmCompiledModule to have
a field "use_trap_handler" that specifies if traps should be used for
the memory accesses in the module being compiled.

Google’s C++ style guide uses uppercase in its examples:

`x` (or `u`) characters at the start, as well as lowercase letters

Like CSP flag 'unsafe-eval', which communicates if both JS source
files and WASM binary files may be compiled, this CL adds a similar
flag for the compilation of WASM binary files.
That is, a WASM binary file will be compiled only if the new flag is
defined, or the flag for 'unsafe-eval' allows it. These flags are
implemented as callback functions on the isolate. The callbacks get a
(CSP) context, and a string, and returns the corresponding value of
the flag.
Both callbacks are initialized with the nullptr, and is used to
communicate that no CSP policy is defined. This allows this concept to
work, independent of it running in Chrome.
It also does a small clean up in api.cc to use macro CALLER_SETTERS,
instead of explicit code when appropriate.

If you just cast those patterns to float or double and pass them
around, the quiet/signaling NaN bit might change. We had several bugs
around this, so add these patterns to the general input vectors.
This oncovers a bug in the wasm interpreter, which will be fixed in a
separate CL.

This is a reland of e737b4ce0d.
The issue on windows bots was fixed in https://crrev.com/c/725733.
Original change's description:
> [test] Avoid unnecessary std::vector allocations
>
> Instead of copying an array of fixed values into an std::vector for
> each usage of the FOR_INPUTS macro, just iterate the constant data
> directly.
> This also makes the <type>_vector() functions return {constexpr Vector}
> instead of {std::vector}.
