HIGHLIGHTS
Bug 94693
"Enhancement - way of making standard library readonly/permanent"
Implemented SCOPE_IS_SEALED, JS_SealObject, JS_UnsealObject, etc. to support
sealed standard object graphs.
Bug 174341
"JS string concatenation performance problem; memory jumps from 16 MB to 250+ MB"
Moved left-associative binary tree flattening from the post-order position
in js_FoldConstants where it was added to NewBinary, where it avoids JSParseNode allocations up front
and reduces recursion in all parse-tree walking.
This change enables js_FoldConstants to see a very long concatenation of
string literals as a PN_LIST node, so it can quickly concatenate without
running afoul of O(n^2) problems inherent in js_ConcatStrings applied to
two atomized strings (the old way of folding string concatenations, still
used for any pairwise string literal concatenation).
Fixed sporadic, Windows-only crashes/anomalies on large integers:
Bug 140852
"String(819187200000) == '8191871:0000' in xpcshell, browser"
Bug 160602
"Large integers, e.g. getTime(), causing crash at 0x39393929"
