The allocator for determining the location (reg/stack) for parameters and return values can be constexpr. This avoids lazy initialization, saving code size and execution time, and simplifying the implementation significantly.

For wide bytecodes, save the bytecode offset as the offset of the prefix bytecode, rather than the bytecode itself. This means that any code that reads the bytecode can explicitly know the width of the bytecode at the offset without having to iterate through the complete bytecode array. Also simplifies some code in the bytecode analysis that had to work around the previous approach.

Jakob Gruber authored
As a first step towards lazy builtin deserialization, this CL moves builtins to their own dedicated area in the snapshot blob, physically located after startup data and before context-specific data. The startup- and partial serializers now serialize all seen builtins as references, i.e. they only encode the relevant builtin id (taking care to preserve special behavior around the interpreter trampoline and CompileLazy). Builtins are later fully serialized by the BuiltinSerializer. The separate blobs are finally glued together by CreateSnapshotBlob. Deserialization takes the same steps: when we see builtin reference bytecodes before builtins have been deserialized, we push to a list of deferred builtin references. After builtin deserialization, this list is iterated and all builtin references are fixed up.

U+feff is the UTF BOM but if it occurs inside the text, it's a "zero-width no-break space". However, the UTF-8 decoder in script streaming still thought it's a BOM and skipped it. The correct way to handle it would be to create a U+feff code point instead - the Scanner will then handle it as whitespace. This is a discrepancy between the Blink UTF-8 decoder and the V8 UTF-8 decoder, and caused the source positions be off by one. This bug went unnoticed, since normally off-by-one in this situation doesn't make the code to break.

This is useful for the RecordWrite stub that can now specify the set of allocatable registers in its call descriptor interface. During register allocation a custom register configuration is used to ensure that the register are allocated from the given set. This makes calling RecordWrite stub less expensive as we need to save/restore only the allocatable registers instead all registers.

In case of LAP(lazy accessor pair), the function's creation context must be equal to the accessor holder's creation context, so this CL changes the current context to the accessor holder's creation context. Note that this is the second attempt after https://crrev.com/2770003002 The change from the previous attempt is to skip looking for the object's constructor if the object itself is a function. Also some of Blink's LAP-context-sensitive tests got updated at https://crrev.com/c/597990 and the rest of the tests will get temporarily disabled at https://crrev.com/c/605408 .
