The main issue was that offsets for GC roots on the stack were being
miscalculated because invokedynamic bootstrap methods are invoked as
static methods but were not being flagged as such.
Also, I forgot to initialize MyThread::dynamicTable in the constructor
(and why the hell doesn't `gcc -Wall` warn me about stuff like that?)
For lambdas that implement java.io.Serializable, the compiler emits
calls to LambdaMetaFactory.altMetafactory, not
LambdaMetaFactory.metafactory, so I've provided a stub implementation
that ignores that currently ignores the extra parameters it receives.
This also fixes a bug in compiling lambda glue code for lambdas that
take longs and/or doubles.
The two big pieces here are basic invokedynamic support and a working
version of LambdaMetaFactory.metafactory. The latter works by
dynamically building a synthetic class with three methods: a static
factory method, a constructor for the factory method to call, and a
method to satisfy the requested interface which defers to the
specified MethodHandle.
This work relies heavily on Avian's specific MethodType and
MethodHandle implementations, which provide extra, non-standard
features to make code generation easier. That means we'll probably
need to use Avian's versions of java.lang.invoke.* even when building
with the OpenJDK or Android class libraries.
