RFR(XS) 8153315: [JVMCI] evol_method dependencies failures should return dependencies_failed

This fixes a minor issue which showed up while debugging Java code.  evol_method dependences can change at any time so it’s just a normal dependence failure not invalid dependencies.  Graal considers it an error to build invalid dependencies so it complained.  Tested under the Eclipse debugger.
