ART: Faster PrettyMethod().
Rewrite DexFile::PrettyMethod() to avoid copying strings.
This improves the performance, especially when requesting
the signature.
Avoid code duplication in ArtMethod::PrettyMethod() and
delegate to DexFile::PrettyMethod().
10 million invocations of ArtMethod/DexFile::PrettyMethod()
for "void Main.main(java.lang.String[] args)" with (+) or
without (-) signature, time in ms:
