[Valgrind-developers] testing

[Jeremy F. <je...@go...>]

I've created a new skin - testbed - for dumping useful test stuff into. 
The first is an implementation of a XUInstr TRASHF, which trashes the
flags between every UInstr as a way of exercising the lazy flags
handling.  It has two command line arguments: --trash-flags=yes|no
(generate logical flag trashing), and --really-trash=yes|no (physically
change the CPUs flags).  --really-trash is really slow.

With --trash-flags=yes --really-trash=yes, big complex things like
mozilla and OO are working fine (albeit slowly).
