[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.

TEST=New vm/dart_2/isolates/deopt/*_test.
