completed. This adds a message test to test that.

- Combine scope_info and name field on SFI into name_or_scope_info field
- Change the name of a couple of SFI accessors: name => Name,
has_shared_name => HasSharedName, set_name => SetName

This CL will temporarily increase memory since the position info

There was a bug in spilling i64 constants, in that the half stack slot
*above* should have been filled with the high word instead of the one *below*.
Instead of just fixing this, this CL optimizes spilling x64 constants to the
stack by emitting shorter and faster code, especially if the constant fits in
31 bits (which is the majority of cases).

A value of type OtherSeqString can change its type to OtherNonSeqString
via inplace internalization (and redirection via a ThinString). This can
lead to out of bounds memory accesses and generally correctness bugs, as
seen with crbug.com/822284.
This change might affect performance in some cases, and we'll need to
evaluate whether it's worth spending cycles on adding another mechanism
that leverages the sequential string information in a safe way on a case
by case basis.

This introduces a new JSCreateTypedArray operator, backed by a dedicated
CreateTypedArray builtin, and adds support to lowering new TypedArray
calls to this operator. This way we avoid the overhead of going through
the generic construct stub machinery for hot code. This not only
recovers the performance regression on the typed array constructor
benchmarks, but even improves slightly beyond what we had in 6.6.
We might in the future try to fully inline the TypedArray constructor
into optimized code for certain cases.

TurboFan assumed that the output of NumberToString is always a
sequential string, since that's what we put into the number to
string table. However we might eventually morph these strings
into ThinStrings when we need to internalize them, in which case
the type in TurboFan will be wrong, and we read out of bounds.
