This CL adds the newline character as a valid character
in Torque strings.
You can now write Print('Hello, World!\n') in Torque and it works!

This CL adds a fast path for DataView getters and setters when the
load or store to be performed is aligned and when the requested
endianness matches the platform endianness.
In that case, we can just emit the right load/store instruction
instead of having to read and write data byte by byte.

In the process:
- Add strict ordering of Types so that name mangling is consistent
and build time. Previously, the UnionType stored the union's
types in a std::set<const Type*>, which did not have a consistent
ordering of the types in the set.
- Add a int31 type to enable consistency and correctness of
handling of 'constexpr int31' values on the C++ side.
- By removing the "implicit" keyword for operators, there is now
one less difference between operators and calls, another
incremental step in unifying operators and calls.
- Enable external (i.e. C++-defined) generic specializations
- Add CSA support for checking double ElementsKinds, including
tests.
- Clean up some constexpr/non-constexpr handling of ElementsKinds.

This CL changes the behaviour of number literals. Large integer
literals (bigger than Smi, but fit into int32) should have
type "constexpr int32" instead of "constexpr float64".

This CL is a proposal to add "checked" casts (CAST in CSA) to the Torque language.
The CL adds the "unsafe_cast<>" operator that emits a "CAST".
Example:
let n: Number = ...;
...
if (TaggedIsSmi(n)) {
let m: Smi = unsafe_cast<Smi>(n);
...
}
The cast wont incur a runtime overhead now.

This CL adds grammar support for function pointers to generic builtins.
It also instantiates generic specializations when they are only used
in an assignment to a function pointer.
Example:
builtin GenericBuiltinTest<T: type>(c: Context, param: T): Object {
return Null;
}
let fnptr: builtin(Context, Smi) => Object = GenericBuiltinTest<Smi>;

This CL adds the new type expression
builtin(Context, ArgType1, ...) => ReturnType
and allows to use Torque-defined builtins as values of this type, as well
as calling values of this type.
The new function pointer types are subtypes of Code.

This CL changes the generated C++ code for LabeledStatementBlocks to
only emit labels if they are used.
Prior to this CL, when a label was only used on one path of an
if constexpr expression, and not at all anywhere else,
the try/label construct would BIND a label that was not used,
causing a CSA verification error.
