Introduces a new VariableLocation MODULE for variables that live in a module's export table. Scope analysis sets this for the approriate variables. Not yet supported by any backend. Also, treats all imports as CONST bindings (including namespace imports), rather than having new special variable modes.

The old code was using VariableMode, but that signal is both over-pessimistic (some CONST and LET variables need no hole-initialization) and inconsistent with other uses of the InitializationFlag enum (such as %LoadLookupSlot). This changes no observable behavior, but removes unnecessary hole initialization and hole checks in a few places, including block-scoped function declarations, super property lookups, and new.target.

This adds verification of bailout IDs to {PrepareFrameState} to ensure all bailout points used for lazy deoptimization have been prepared by full codegen.

This runtime function now also works for Ignition generators. It returns the source position of the yield at which a suspended generator got suspended.

Runtime_DeclareLookupSlot is used when generating code for var and function declarations originating in an eval. Over time, it's accumulated quite a bit of cruft, which this CL removes: - With legacy const gone, lookup slots never have any property attributes. - There was a bit signaling that the variable was from an eval, but that was redundant since DeclareLookupSlot is only used for eval. - Some Proxy-related code didn't make sense here. Its name was also not terribly clear: while "LookupSlot" is used in several places, this particular function is only used for declaring variables and functions inside sloppy eval. Renamed (and split into two) to make this clear for future archeologists. Also added various DCHECKs to check the assumptions being made.

This was initially used to special case some weird date.js behavior, but has since been abused in other areas. In case of the string character access, everything that is outside the Smi range cannot be a valid string index anyways, so %NumberToSmi is perfect here in either case, and for ToPositiveInteger it's better to just use ToInteger adding +0 to turn -0 into +0.

Rewrite decodeURI and decodeURIComponent as builtin functions and install them in the bootstrapper. Delete unused runtime functions: - TruncateString - NewString - OneByteSeqStringGetChar - OneByteSeqStringSetChar - TwoByteSeqStringGetChar - TwoByteSeqStringSetChar Add regression test for decoding large strings. Clusterfuzz detected a problem with %TruncateString, see https://bugs.chromium.org/p/chromium/issues/detail?id=612109#c6 This is automatically fixed by this rewrite because %TruncateString is deleted anyways.
