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.

Benedikt Meurer authored
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.
