RFR(S) 8205105: VM crashes with "assert(Universe::heap()->is_in_reserved(start + words - 1)) failed: not in heap

[Vladimir Kozlov]

Why Graal is affected even when LOHP is not used?

I don't see changes which mapped new TLAB fields added by Low-Overhead 
Heap Profiling.

I don't see your answers to Stefan's comment in bug report about Graal's 
code which is not fixed for _allocation_end.

Does Graal still use fast TLAB refill as default mode?

FastTLABRefill was deprecated by 8194084: "Obsolete FastTLABRefill and 
remove the related code":

http://hg.openjdk.java.net/jdk/jdk/rev/9010e596f391

Should we remove it from Graal too?

Thanks,
Vladimir
