RFR (S): 8004018: Remove old initialization flags

[Erik Helin]

Hi all,

this change removes the three developer flags:
- InitializeJavaLangSystem
- InitializeJavaLangString
- InitializeJavaLangExceptionsErrors

The flags InitializeJavaLangSystem and InitalizeJavaLangString crashes 
the VM when they are set to false (see Testing).

The flag (InitializeJavaLangExceptionsErrors) does not crash the VM when 
just running "-version". The RFE suggests that it should be removed, so 
I went ahead and removed it. Should we keep it?

Testing:
Running a fastdebug build results in the following:

java -XX:-InitializeJavaLangSystem -version
# A fatal error has been detected by the Java Runtime Environment
#   Internal Error (linkResolver.cpp:902)
#   assert(resolved_method->method_holder()->is_linked()) failed: must 
be linked

java -XX:-InitializeJavaLangString -version
# A fatal error has been detected by the Java Runtime Environment
#   Internal Error (linkResolver.cpp:902)
#   assert(resolved_method->method_holder()->is_linked()) failed: must 
be linked

Thanks,
