RFR(S) 8194271: jaotc crashes with --debug flag

[Igor Veresov]

The change fixes the crash that occurs when jaotc tries to print method disassembly. The problem is that HotSpotCompiledCodeBuilder.createCompiledCode() assumes that if its method argument is null it’s a stub. And stub always has a name. The absence of a name caused the crash later on in the C++ code in CodeInstaller::install().

The solution is to pass method name to HotSpotCompiledCodeBuilder.createCompiledCode(). I also strengthened the C++ to throw an exception instead of crashing if a stub doesn’t have a name.
