RFR (XS): hs_err prints "ERROR in GC mode" instead of "Shenandoah"

[Aleksey Shipilev]

Hi there,

hs_err prints this for Shenandoah crashes:

# Java VM: OpenJDK 64-Bit Server VM
(9-internal+0-2016-09-14-171552.shade.shenandoah-jdk9, mixed mode,
tiered, ERROR in GC mode, linux-amd64)

Trivial fix:

diff -r 4f031b39d689 src/share/vm/utilities/vmError.cpp

 }

Okay to push?

Thanks,
