This is a revert of the following changes :

30c475a2046951a81769c2db0b2dad66cd71e189.
lambda: Minor capture-variable/liberate-variable clean-up after post-merge reviews.

6918bf13eb855b3aa8ccdddda2d27ae8c60cec56.
lambda: Experimental support for capture-variable and liberate-variable

fc1ccd740b7c8e96dfac675cfc580122cd1b40a6.
lambda: Infrastructure to support capture/liberate-variable dex opcodes

e2facc5b18cd756a8b5500fb3d90da69c9ee0fb7.
runtime: Add lambda box/unbox object equality

2ee54e249ad21c74f29a161e248bebe7d22fddf1.
runtime: Partially implement box-lambda and unbox-lambda experimental opcodes

158f35c98e2ec0d40d2c032b8cdce5fb60944a7f.
interpreter: Add experimental lambda opcodes for invoke/create-lambda

a3bb72036f5454e410467f7151dc89f725ae1151.
Added format 25x to dexdump(2).

Plus surrounding cleanups.

Test: make test-art
