Avoid removing new-instance instruction twice.
Includes a fail-before/pass-after regression test.
Rationale:
In some corner cases, one new instance reached more than one
java.lang.String.<init> method call. As a result, the new
instance instruction appeared multiple times in the vector
uninitialized_strings_. A second removal crashes the compiler.
This change list avoid the crash by simply skipping instructions
that are already removed.
