Full-featured compiled printf

This translates script-level printf statements into unrolled printing
statements.  This passes all systemtap.printf/*.exp tests.  The compiled code
is faster, variably, but up to 20% improved in my testing.  It also results in
larger .text though, especially when it gets fanned out for something like
"syscall.*".  That might be mitigated by moving this translation to create
functions in pass-2, so identical printfs can share the unrolled code.
