38daeffb9b Issue #2678 - Avoid QIing for NoteXPCOMRoot.
This callback is only used in very limited ways, so just require that the
caller passes in the canonical supports pointer plus the participant.

This probably won't affect performance much.

845d36d582 Issue #2305 Part 2: Support .indices in match result template objects
Before match indices, all match results had the same shape. (If there are
no named capture groups, `.groups` exists but is undefined.) Match results
with `.indices` have a distinct shape, so we need a distinct template
object. We also need a template object for `.indices` itself.

b1fd3b72cf Make NetBSD/powerpc use the powerpc atomic ops.

so add that to the preprocessor ifdef cascade to select atomic
ops.

f4b6cee0cc Issue #2543 - adjust toFixed precision range according to spec update.
As pointed out in the ecma-262 spec change discussion, the behavior is
inconsistent for negative numbers because the exponential fallback assumes
all the digits will be displayed. The negative support was motivated just
by consistency, without any particular concrete use cases, and it's not
supported in other browsers, so this patch removes negatives.

40c9102d6d [js gc] Suppress GC during JSObject::swap
We already suppressed GC for part of this, but we may sweep before the pre-write
barrier is established.
The simplest and safest thing is to suppress GC for the whole method.

e65b46ba0f Issue #2350 - Part 2: Allow "maximumFractionDigits" option in Intl.NumberFormat to be less than the default minimum fraction digits.
This implements the changes from the "has consensus" PR in TC39
The second pair of `DefaultNumberOption()` calls was inlined, because
only the fallback case is relevant anyway.

Steps 12.d and 12.e from the spec PR were combined into a single
`if`-block. That way it also matches step 12.f more closely.
Also changed the single `if` steps into an `if-else if` chain, because
the steps are mutually exclusive.
