1526324 - Stop serializing JSScript::needsArgsObj in XDR

Status: RESOLVED FIXED

(Core :: JavaScript Engine, enhancement, P3)

Description

[Ted Campbell [:tcampbell]]

After the split of script flags into mutable and immutable, it becomes clear that needsArgsObj flag is the only mutable flag that XDRScript preserves. To simplify code and remove special cases we should remove this as no other performance hinting is preserved in XDR.

DRScript should only be preserving ImmutableFlags for consistency.
While preserving the flag might have helped in some cases, it was a
special case of preserving performance hints and should be removed for
simplicity.
