Do not execute OAT files that require app images that cannot be loaded
This change creates a new requires-image flag in the OAT header, which
is set when the file was created with an image (app image, etc.). If
this flag is set, we will not load the OAT file as executable if the
image could not be loaded.
Going forward, this allows the compiler to assume there will be an app
image when an app image is generated and in some cases generate better
code.
Note that we still must load the OAT file, because there will not always
be another way to access the underlying DEX files.
