[JSC] Throw RangeError if Set methods are called on an object with negative
"size" property
https://bugs.webkit.org/show_bug.cgi?id=267494
<rdar://problem/121310940>
Reviewed by Justin Michaud and Yusuke Suzuki.
This change implements steps 6-7 of GetSetRecord [1], ensuring a RangeError is
thrown if
result of ToIntegerOrInfinity is negative, and extracts always-inlineable
@getSetSizeAsInt().
These methods are at stage 3 of ECMA-262 standardization process, meaning we
shouldn't worry
too much about performance impact.
Aligns JSC with V8, preventing most of newly-added Set methods from returning
wrong results
when given an malformed Set-like object.
