Comment out assertions added in JDK-8351443 from AbstractStringBuilder.ensureCapacityNewCoder that increase the codesize, preventing some inlining, and reducing performance
assert coder == newCoder || newCoder == UTF16 : "bad new coder UTF16 -> LATIN1";
assert count <= newCapacity : "count exceeds new capacity";
