Optimize JNI:GetStringRegion() for compressed strings.
Looking at the disassembly, it seems clang++ was unable to
optimize this properly, probably due to possible aliasing,
despite inlining the String::CharAt() and seeing all the
String::IsCompressed() expressions.
Explicitly use the fact that the string is compressed to
optimize the function and similar patterns in JNI.
