Various changes to support OSF1 emulation:
* Move the user stack from VM_MAXUSER_ADDRESS to a place below the 32bit
boundary (needed to support 32bit OSF programs). This should also save
one pagetable per process.
* Add cvtqlsv to the set of instructions handled by the floating point
software completion code.
* Disable all floating point exceptions by default.
* A minor change to execve to allow the OSF1 image activator to support
dynamic loading.
