Three day week.

[GNU-180 # Fix gcov crash on program exit]

Fiddled around with TI-RTOS for a while before I realized that was sort of beside the point. Gave the reporter a method do avoid dumping during the global destructors. Still need to look into where the reported stack space problem might be.

[Upstream]

Out-of-line softmmu patches got some work. Added ppc64 support. Fixed a race and a code removal crash. Emilio verified -5% aa64 boot+shutdown time, but it performed less well on spec2006.

Reviewed risc-v host patch set.
