the assember was getting fiddly. It now masks out only the undefined or unimplemented parts of the feature set bits, so it now passes through all the non-ISA-related feature bits to clients. It also leaves the vendor ID string unmolested, so that clients can extract vendor-specific information like extended brand strings and cache/TLB configuration info. It does, however, implement some Valgrind-specific requests at 0xd8000000, though at present the only functionality is the ValgrindVCPU signature. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2236
