Upon return from a syscall handlers, the r1, r2, and r3 registers could contain random kernel data that should not be leaked to user mode. Zero these out before returning from _arm_do_syscall(). Fixes #7753. The invocation macros need a clobber if r1, r2, or r3 are not used to carry syscall arguments. This is a partial fix for #7754 but there appear to be other issues.
