Switched List implementation from a custom heap allocator to an inline
Vector, for a disappointing .5% SunSpider speedup.

Also renamed List::slice to List::getSlice because "get" is the
conventional prefix for functions returning a value through an out
parameter.

kjs/array_object.cpp: (KJS::ArrayProtoFunc::callAsFunction): Removed some redundant function calls and memory accesses.

kjs/bool_object.cpp: (BooleanObjectImp::construct): Removed questionable use of iterator.

kjs/list.cpp:
kjs/list.h: New List class, implemented in terms of Vector. Two interesting differences:
1. The inline capacity is 8, not 5. Many of the Lists constructed during a SunSpider run are larger than 5; almost none are larger than 8.

The growth factor is 4, not 2. Since we can guarantee that Lists aren't long-lived, we can grow them more aggressively, to avoid excessive copying.

kjs/regexp_object.cpp: (RegExpObjectImp::construct): Removed redundant function calls.

kjs/string_object.cpp: (KJS::StringObjectImp::construct): Removed questionable use of iterator.

wtf/Vector.h: (WTF::::uncheckedAppend): Added a fast, unchecked version of append.
