Reviewed all tapset functions. Ones that
use CONTEXT->regs:
registers_valid() valid, only nullness test
user_mode() valid, only to test user mode flag in MSR
stp_pid() only mentioned for completeness; uses task_pt_regs() only
ucontext-unwind.stp:*: unsure, maybe should task_pt_regs() only; mjw?
utrace.stp: Ditto. Actually, should rewrite src/tapset-utrace.cxx
to use expression embedded-c and remove these tapset fns entirely.
