Martin Kustermann	6127386cfa	[vm/compiler] Ensure allocate instructions have correctly pruned lazy deopt environment ... Since allocation instructions can throw OOM exceptions, they require deopt information. In general it's rather hard to test that this deopt information is correct. In order to test this, this CL makes those IR instructions support lazy deopt and add tests that exercise this deopt sequence, thereby ensuring the deoptimization environment is correct.
