Move quick frame info to OatQuickMethodHeader.
Rename OatMethodHeader to OatQuickMethodHeader, move frame
info from OatMethodOffsets to OatQuickMethodHeader. Retrieve
the info from other places for non-quick methods (portable
compiled bytecode or jni stub, generic jni, runtime,
abstract and proxy).
This change has a libcore/ companion CL
"Remove ArtMethod's quick fields for frame size and spills."
