interpreter: Add experimental lambda opcodes for invoke/create-lambda
These opcodes are not yet fully specified, and *will* change before they become shippable.
Do not write production code against experimental opcodes.
--
Implement partial interpreter support for new dex instructions invoke/create-lambda, and a
new opcode format 25x.
* Does not verify, in fact verification will soft fail when we see those opcodes.
* Compilers will punt to interpreter since they don't support new opcodes.
* As there is no way to capture/liberate variables yet, the "closure" is just
an ArtMethod for the time being.
All new opcodes are disabled by default, use runtime option -Xexperimental-lambdas to enable them.
For example:
dalvikvm ... -Xexperimental-lambdas ...
dex2oat --runtime-arg -Xexperimental-lambdas ...
