RFR (XS): JDK-8014430: JRE crashes instead of stop compilation on full Code Cache. Internal Error (c1_Compiler.cpp:87)

[Azeem Jiva]

Looks good to me (although I'm not an official reviewer).  One recommendation is to reword the error message to be more descriptive.  Maybe "Compiler code cache exhausted, increase using -XX:ReservedCodeCacheSize=."
