MIPS32r2: Fix Chromium runtime crash

Crash is caused by ldxc1 instruction, which traps when double values are
not aligned on 8-byte boundaries. Problem was tracked to SkChunkAlloc which
produces pointers aligned on 4-byte boundaries leading to misalignment.

This change makes sure that SkChunkAlloc will produce pointers that are
aligned to 8 bytes.

Appropriate tests are added to tests/MemsetTest.cpp
