Optimizing: Determine invoke-static/-direct dispatch early.
Determine the dispatch type of invoke-static/-direct in a
special pass right after the type inference. This allows the
inliner to pass the "needs dex cache" check and inline more.
It also allows the code generator to avoid requesting a
register location for the ArtMethod* for kDexCachePcRelative
and direct methods.
The supported dispatch check handles also situations that
the CompilerDriver currently doesn't allow. The cleanup of
the CompilerDriver and required changes to Quick will come
in a separate change.
