Pretty Printer for a WTF::Vector.
The output of this pretty printer is similar to the output of std::vector's
pretty printer, which is bundled in gcc.
Example gdb session should look like:
(gdb) p v
$3 = WTF::Vector of length 7, capacity 16 = {7, 17, 27, 37, 47, 57, 67}
(gdb) set print elements 3
(gdb) p v
$6 = WTF::Vector of length 7, capacity 16 = {7, 17, 27...}
(gdb) set print array
(gdb) p v
$7 = WTF::Vector of length 7, capacity 16 = {
7,
17,
27
...
}
(gdb) set print elements 200
(gdb) p v
$8 = WTF::Vector of length 7, capacity 16 = {
7,
17,
27,
37,
47,
57,
67
}
