Change default alignment of pool allocator to pointer-aligned The translator uses the pool allocator with its default alignment. The alignment was previously 16, which is unnecessary. That is changed to sizeof(void *) such that allocations are pointer aligned. Running TracePerfTest.Run/vulkan_manhattan_10 on Linux, the total size of allocations made by this class for the translator goes down from 376832 bytes to 360448 bytes for a ~4.3% improvement.
