RFR (s) 8148772: VM crash in nsk/jvmti/RedefineClasses/StressRedefine: assert failed: Corrupted constant pool

[Coleen Phillimore]

Summary: ConstantPool::resolve_constant_at_impl() isn't thread safe for 
MethodHandleInError and MethodTypeInError.

Need to ignore the InError tag when fetching method_handle_index and 
method_type_index.  The error is cached after the call to 
systemDictionary::link_method_handle_constant() if it's not there already.

Tested with rbt equivalent of nightly runs, and StressRedefine test 
(reproduceable with this error) for >24 hours (also with 8151546 
fixed).  Ran jdk/test/java/lang/invoke tests.  I can't write a test for 
this because it's too timing sensitive.
