[WTF] Add Malloc::nextCapacity feature and leverage it in
InstructionStreamBuffer
https://bugs.webkit.org/show_bug.cgi?id=279212
rdar://135358535
Reviewed by Keith Miller.
InstructionStreamBuffer gets shrinked at last. So increasing the size rapidly
does not matter. And we know that this is a bottleneck in
BytecodeGenerator. This patch adds Malloc::nextCapacity which controls the next
capacity based on the curent capacity. And we use customized
function for InstructionStreamBuffer.
