Subject: [PATCH] Cherry-pick 252432.839@safari-7614-branch (71cdc1c09ef1).
rdar://102531234
The provenType filtering in FTL's speculateRealNumber is incorrect.
https://bugs.webkit.org/show_bug.cgi?id=248266
<rdar://problem/102531234>
Reviewed by Justin Michaud.
speculateRealNumber does a doubleEqual compare, which filters out double values which
are not NaN. NaN values will fall through to the `intCase` block. In the `intCase` block,
the isNotInt32() check there was given a proven type that wrongly filters out ~SpecFullDouble.
Consider a scenario where the edge was proven to be { SpecInt32Only, SpecDoubleReal,
SpecDoublePureNaN }. SpecFullDouble is defined as SpecDoubleReal | SpecDoubleNaN, and
SpecDoubleNaN is defined as SpecDoublePureNaN | SpecDoubleImpureNaN. Hence, the filtering
of the proven type with ~SpecFullDouble means that isNotInt32() will effectively be given
a proven type of
{ SpecInt32Only, SpecDoubleReal, SpecDoublePureNaN } - { SpecDoubleReal, SpecDoublePureNaN }
which yields
{ SpecInt32Only }.
As a result, the compiler will think that that isNotIn32() check will always fail. This
is not correct if the actual incoming value for that edge is actually a PureNaN. In this
case, speculateRealNumber should have OSR exited, but it doesn't because it thinks that
the isNotInt32() check will always fail and elide the check altogether.
In this patch, we fix this by replacing the ~SpecFullDouble with ~SpecDoubleReal. We also
rename the `intCase` block to `intOrNaNCase` to document what it actually handles.

[JSC] ToThis object folding should check if AbstractValue is always an object
https://bugs.webkit.org/show_bug.cgi?id=251944
rdar://105175786
Reviewed by Geoffrey Garen and Mark Lam.
ToThis can become Identity for strict mode if it is just primitive values or its object does not have toThis function overriding.
This is correct, but folding ToThis to Undefined etc. (not Identity) needs to check that an input only contains objects.
This patch adds appropriate checks to prevent from converting ToThis(GlobalObject | Int32) to Undefined for example.

CloneDeserializer::deserialize() should store cell pointers in a MarkedVector.
https://bugs.webkit.org/show_bug.cgi?id=254797
rdar://107369977
Reviewed by Justin Michaud.
Previously, CloneDeserializer::deserialize() was storing pointers to newly created objects
in a few Vectors. This is problematic because the GC is not aware of Vectors, and cannot
scan them. In this patch, we refactor the MarkedArgumentBuffer class into a MarkedVector
template class that offer 2 enhancements:
1. It can be configured to store specific types of cell pointer types. This avoids us
having to constantly cast JSValues into these pointers.
2. It allows us to specify the type of OverflowHandler we want to use. In this case,
we want to use CrashOnOverflow. The previous MarkedArgumentBuffer always assumes
RecordOnOverflow. This allows us to avoid having to manually check for overflows,
or have to use appendWithCrashOnOverflow. For our current needs, MarkedVector can be
used as a drop in replacement for Vector.
And we fix the CloneDeserializer::deserialize() issue by replacing the use of Vectors
with MarkedVector instead.
