Regression in MH building for catchException?

[Charles Oliver Nutter]

JRuby invokedynamic bindings that use catchException appear to blow up
with a current MLVM build (as of a few minutes ago). The error is the
same in every case:

Caused by: java.lang.IllegalArgumentException: spread on
invoke_F9(CacheEntry,ThreadContext,IRubyObject,IRubyObject,String,IRubyObject,IRubyObject,IRubyObject,Block)IRubyObject
with Object[]
	at java.lang.invoke.MethodHandleImpl.spreadArguments(MethodHandleImpl.java:764)
	at java.lang.invoke.MethodHandleImpl.spreadArguments(MethodHandleImpl.java:751)
	at java.lang.invoke.MethodHandleImpl.makeGuardWithCatch(MethodHandleImpl.java:1152)
	at java.lang.invoke.MethodHandles.catchException(MethodHandles.java:2139)
	at org.jruby.runtime.invokedynamic.InvokeDynamicSupport.<clinit>(InvokeDynamicSupport.java:1356)

The same catchException call works properly on current macosx build. I
have not done any bisecting to determine what openjdk/mlvm commit
introduced this problem.

Reproducible with even the fib benchmark by running this way:

jruby -d -X+C --server bench/bench_fib_recursive.rb 10 35
