Update dexopt control logic

This adds a new mode, -Xdexopt:full.  In most ways it behaves like
-Xdexopt:verified (the default), but when an un-optimized class is
loaded we will do a full set of optimizations instead of just the
"essential" set.

For classes that are verified and optimized by dexopt (which is to
say, most of them), this has no effect.  For the others, this trades
off speed for space, substituting quickened instructions but causing
copy-on-write of pages mapped from the DEX file.

This also demotes the substitution of execute-inline opcodes to
"non-essential" status.
