Created an attachment (id=121216)
 --> (https://bugs.webkit.org/attachment.cgi?id=121216&action=review)
patch updated

Update the patch to _not_ adjust the spill order for 64bit, i.e. still Integers have lower priority to be spilled as there may be additional operations - in some cases the spilled integers are boxed as JS integers when being filled (btw, is it necessary?). The regression of the last patch on imaging-gaussian-blur should be caused by this.
So this patch keeps the spill order for 64bit as is, but simply modifies the comments a bit to better describe the reason, and also removes SpillOrderBoolean for 64bit as it's never used.
