RFR (12) JDK-8218025: disable pop_frame and force_early_return caps for Graal

[Igor Ignatyev]

Hi Alex,

UseJVMCICompiler is declared only if INCLUDE_JVMCI is defined, so your current patch will break builds where it's undefined. the rest (esp. problem list ;) ) looks good to me.

adding hotspot-compiler alias.

Thanks,
-- Igor
