X86: If SSE4.1 is missing lower SMUL_LOHI of v4i32 to pmuludq and fix up the high parts.

This is more expensive than pmuldq but still cheaper than scalarizing the whole thing.

X86TTI: Adjust sdiv cost now that we can lower it on plain SSE2.

Includes a fix for a horrible typo that caused all SDIV costs to be
slightly off :)

Add emitThumbSet to the arm target streamer.

This fixes the asm printer implementation and lets the parser be unaware of
what .thumb_set is.

Teach the pass manager's execution dump to print the current time before
each line. This is particularly nice for tracking which run of
a particular pass over a particular function was slow.

This also required making the TimeValue string much more useful. First,
there is a standard format for writing out a date and time. Let's use
that rather than strings that would have to be parsed. Second, actually
output the nanosecond resolution that timevalue claims to have.

This is proving useful working on PR19499, so I figured it would be
generally useful to commit.

Update tests to use the new format of printing a TimeValue. It's a bit
odd to have the output of 'llvm-ar tv' depend on the format of
TimeValue::str(), but that's what we have today. If anyone needs the
output to remain compatible with GNU ar or old versions of llvm-ar, just
shout and I'll switch the code to manually format its times.

Note that there isn't a portable format -- Mac and GNU have different
formats at least (thanks Rafael!) so...
